Mounting is supposed to be done when the camera is turned off, however, for this review, I risked destroying the lens by attaching it with the camera turned on, just for kicks, and nothing bad happened. You can also mount the lens upside down, just like a hood and everything still works fine. Attaching the converter is about the same as putting on a hood: align the orange dots, push and turn clockwise until you hear a click. Unmount by pushing the black tab up and turning until loose.
General: Do not apply this product if the surface temperatures are below 50F. Store in a cool, dry place, protected from freezing or temperatures above 100F. For long-lasting protection of iron surfaces, the cured rust converter coating should be sealed with two coats of high-quality oil-based paint. No other primer is required.

Traditionally, these polarization-conversion devices have been designed using birefringent materials such as liquid crystals and quartz that in essence require relatively large thickness but provide a narrow-band performance. Recently, the design of polarization converters is based more on two-dimensional (2D) structures called metasurfaces. These metasurfaces contain a periodic array of sub-wavelength resonant structures. The phase of an incident terahertz wave can be desirably controlled by those resonators to yield polarization conversion in wideband. Moreover, due to their low profile, usually
In this work, we present a free-standing three-layer transmissive polarization converter that can efficiently rotate a linearly polarized terahertz wave by 90. To enhance the bandwidth, we include two resonators, a split-ring resonator (SRR) and an H-shaped resonator, in the middle layer. Moreover, a low-loss dielectric, cyclic olefin copolymer (COC), is employed as the dielectric support and spacers. Although by far less lossy than most polymers, the COC usage in multi-layer terahertz devices has not widely been embraced since the normal spin-on fabrication technique was not successful. For the first time, we employ an unconventional fabrication technique involving multiple polymer bonding and photolithography steps to realize the three-layer polarization converter with the COC dielectric. The spectral responses of the fabricated device are experimentally validated with terahertz time-domain spectroscopy and the vector network analyzer.
The transmissive polarization converter design proposed here is made up of three metallic layers in a multi-layer structure similar to that proposed by Grady et al.11 and also demonstrated by Chang et al.26 Herein, the cyclic olefin copolymer is employed as the dielectric spacer, and a SRR and an H-shaped resonator are combined in the middle layer. A three-dimensional (3D) view for one unit of the proposed polarization converter is shown in Fig. 1(a), while the corresponding two-dimensional (2D) view of the three different layers labeled A, B, and C is shown in Fig. 1(b). The unit cell is a square of side p = 154 μm. The top and bottom layers are made of gold (Au) wire gratings of width n = 8 μm and separation m = 6 μm, placed orthogonally to each other. The separation between the middle layer and each grating, t, is 74 μm. All other dimensions are given in the caption of Fig. 1. To realize a free-standing device, the bottom grating is supported by a 3 μm layer of COC. The thickness of all metallic (gold, Au) layers is 200 nm.
Unit cell of the proposed polarization converter. (a) 3D view of the unit cell with all three metallic layers and dielectric spacers. (b) 2D view of the excited front layer, middle resonator layer, and back layer. The dimensions of structural parameters are as follows (all in μm): p = 154, m = 6, n = 8, l = 133, w1 = 8, w2 = 14, s = 4, q = 14, g = 6, t = 74, and t0 = 3.
The proposed polarization converter is designed by numerically evaluating the spectral response of plausible middle-layer resonators using 3D finite-element full-wave simulations conducted with the frequency-domain solver in CST Microwave Studio. The main idea is the inclusion of multiple resonators in the middle layer to introduce multiple resonances. In our simulation, Floquet boundary conditions are employed in the x- and y-directions of the unit cell. The frequency-dependent surface impedance that accounts for the Ohmic losses27 of Au is used for all metallic layers. The COC is modeled with a relative permittivity and loss tangent (tan δ) of 2.324 and 0.0007, respectively, similar to values reported in the literature.28,29 The simulation results are compared with the experimental results in the Results and discussions section.

The arrows indicate the directions of the surface current.
From the almost similar cross-polarization conversion of the reflective- and transmissive-mode polarization converters, which are based on the SRR and H resonator, we can deduce the same conversion mechanism for the three-layer polarization converter in the transmission mode. As denoted in Fig. 2(b), the H resonator strongly enhances the cross-polarization conversion at high frequencies and assists in broadening the bandwidth of the polarization converter. That is, by including the H resonator, the number of resonant modes is increased. Moreover, by applying the grating lobe equation, the onset of diffraction based on the unit cell dimension, p = 154 μm, at normal incidence, appears at 1.95 THz.32 This implies that multiple resonators could be added to further enhance the bandwidth.
In Table I, we present a comparison between different transmissive polarization converters demonstrated in the literature, based on their bandwidth at the conversion efficiency greater than 80%. Our results show a marked improvement in the bandwidth and efficiency relative to practical devices.
I want to design a dc-dc boost converter and manage power (MPPT) for an ultra-low power fuel which contains input voltage < 1 V and input current < 500 uA.if I choose simple boost converter, I will have problem with inductor design because low input current (about 500 uA) will cause extremely high inductor.
I need to choose high freq and high L that means an inductor with more than 10 mH inductance and work in 5 MHz freq. (we don't have inductance in this spec)what should I do for power managing of this ultra-low fuel?
The Sony NEX-C3 was used for this review. For a better understanding of terms and methods used in this review, go here. The usual center, mid-section and corner crops are located at the very bottom of the page.
Introduction. Sony designed the NEX 16mm F/2.8 pancake lens to be used with a couple of different converters, one of which is the ultra wide angle 0.75x, the other is a fisheye. This converter gives you the same coverage as 12mm, or 18mm in full frame (135 film) format; that's pretty wide! The made in Japan converter uses the focusing of the 16mm host lens, so there are no contacts for communication with the camera, and the EXIF data displays 16mm, so the camera doesn't know it's mounted. Fit and finish: the same as other Sony NEX lenses. It seems like Sony is using the same outer 'aluminum alloy' material, and the color matches the silver lenses perfectly. The converter comes with a built-in hood, and can't be removed. The front and rear covers are non-traditional for Sony lenses; they're just plastic covers the fit snugly in place. Light loss when using the converter is approximately a half stop, so the minimum equivalent aperture would be around F/3.2-3.5. Mounting. The converter mounts to the front of the 16mm lens just outside of the filter threads. You can mount it upside down if you want, meaning the same as a bayonet type hood. It doesn't seem to make any difference in image quality. There is a red dot on the converter that you match up with a red dot on top of the lens, that way you don't have to worry about mounting it wrong.
