Sinc pulse excitation inclined at an angle

[Payal Bhattacharjee]

Hello everyone,

Is it possible to apply a sinc-pulse excitation field in the x–y plane at an arbitrary angle θ? I attempted the implementation shown below, but it is not working correctly. Could you please help me identify and fix the issue? 

Thank you in advance.

// parameters for the sinc function
Amp := 0.001
fmax := 100e9
t0 := 1e-12
theta := 30 * pi/180    
c1 := cos(theta)
s1 := sin(theta)
dir := vector(c1, s1, 0)
B_ext = Amp * sinc(2*pi*fmax*(t - t0)) * dir

Hi Payal,

In your code you are supposing that the scalar vector multiplication is  implemented in the scripts of mumax. In fact, it is a complex implementation that is not considered. It will work if you multiply the components. Maybe, one has to check but I think that the following lines should work:

theta := 30 * pi/180    

B_ext =  vector(Amp * sinc(2*pi*fmax*(t - t0)) *cos(theta),  Amp * sinc(2*pi*fmax*(t - t0)) *sin(theta) , 0)

Best regards,

Felipe

Thank you, Felipe, once again. It worked.
