Re: Does anyone have any experience in the retrival of metamaterials

hi,

Can anybody please clarify this...i have got this from the smith srr+wire hfss file

mag(S21)*(cos(-ang_deg(S21)) + cmplx(0, 1)*sin(-ang_deg(S21)))
mag(S11)*(cos(-ang_deg(S11)) + cmplx(0, 1)*sin(-ang_deg(S11)))

I have read smith paper but don't know where this equation comes from?

I will appreciate if anybody can please get back to me urgently...

hello Mr fangjing
can you help me how did you overcome this discontinuity in the pahse and when can i delete ir add 2*pi?

i worked on smith paper and the results of s11 and s21 is exactly but the phase isn't true so the permitivity and refractive index isnot true.

Hi fangjing,what do you mean by index=-1i.*log(eink0d)./k_0./cell_thickness;In Smith's paper no where there is any expression of log,then from where you got this ?

Please anyone tell me that during the simulation of unit cell of srr, what should be the height of unit cell setup in HFSS, as length and width will be same as the length and width of unit cell of srr. Also, tell me about the waveport assignment, how i can set the polarization of electric field as given in examples.

please any one tell me, what should be the height (d) of unit cell in the simulation setup of HFSS.

-2pi is added in the exponent part, why 2pi change will change the finally caculated value?

Hi everybody...

CG0210794 please, could u give me your SSR dimensions (thickness, gap, width, lenghts for both rings)?
I′m doing something similar, but I don not get the correct resonation.

Thanks a lot
