FW: Seminar on Terahertz Plasmonics and metamaterials and their applications to Biology and Communications

[Hu Junhao]

Dear All,

 

FYI,

 

Regards,

Junhao

 

Technical Seminar Jointly Organized by

School of EEE, NTU and IEEE Photonics Society Singapore Chapter

 

 

You are cordially invited to a seminar on

 

Terahertz Plasmonics and metamaterials and their applications to Biology and Communications

 

 

Speaker:    Professor Tahsin Akalin, IEMN, University of Lille 1, France

 

Time/Date:   2:30pm to 4:00pm, 28 June 2011 (Tuesday)

 

Venue:          Meeting Room, S2-B2B-77, School of EEE, NTU                  

 

Abstract:  The talk will be dedicated to THz Plasmonics and Metamaterials. Is is divided in three parts. In the first part, a brief review of the main contributions to this field will be presented. The second part concerns the study of a compact Planar Goubau Sommerfeld Line (PGSL) coupled to metamaterials and which enable the control of surface electromagnetic waves from GHz to THz frequencies. High quality factor resonances are achieved with different shape of ring resonators. In the last part, these PGSL are also used in an original topology for THz microscopy. We will present an approach with a single PGSL and a second one with two PGSL placed very close to each other. Recent work on THz plasmonic arrays will be also presented. This work is the fruit of collaboration with the group of Prof. Willie Padilla (Boston College) and the group of Prof. Mario Sorolla (UPNA).

 

About the Speaker: 

Tahsin AKALIN is an Associate Professor at IEMN (Institute of Electronic, Microelectronic and Nanotechnology) and at the University of Lille 1, France (USTL / IUT-A) since 2004. He received his M.S and PhD degrees on Electronics in1999 and 2002 from the University of Lille. During his thesis he has developed passive structures such as filters based on periodic structures (PBG). He has also been involved in the study of directive antennas with EBG superstrates. He has studied metamaterials with simultaneous negative permittivity and permeability at microwave frequencies and now he is more interested at terahertz frequencies. His research activities have also concerned the development of original BioMEMS for the characterization of living cell and neuronal entities by means of GHz and THz waves. He has developed high resolution BioMEMS with the use of original transmission lines at THz frequencies: Planar Goubau-Sommerfeld Lines (PGSL). He has invented an original and planar solution for the excitation of a Goubau mode via tapered CPW. The lines combined with resonators and active devices can be used for THz applications like THz communications. He is also involved in the study of THz plasmonic structures with the aim of applications for THz Near Field Microscopy and for THz antennas which are combined with Quantum Cascade Lasers (QCL) to improve their power emission properties (beam-shaping and power level). He is co-author of more than 60 international communications (including journals and conferences) and he has given more than 15 invited talks for international conferences (ICMAT, Meta’10, Metamaterials, SICAST, POEM etc)

 

He is a reviewer for:

-IEEE (Institute of Electrical and Electronics Engineers): Trans. On MTT, TAP and AWPL

-AIP (American Institute of Physics): APL and JAP

-OSA (Optical Society of America): Optics Express

 

He is an expert for french national research agency ANR since 2005. He is a TPC member of several major conferences: IRMMW-THz, OTST, IEEE-APMC, and of Meta'10. He is the organizer, chairman and co-editor of several special sessions and special issues on THz and Optical Plasmonics and Metamaterials for international conferences and journals. Since 2011, he is a European Microwave Lecturer (EML) for the European Microwave Association (EuMA). He is a member of the IEEE French Bureau for MTT and TAP societies. He is also a member of several societies: IEEE (Photonics, MTT, TAP), OSA and EOS.
