Hi all,
the attachment is my wedge simulation following the one in the paper OE vol.17, 2198(2009). seems there is some problem in my work because at 1.36um and 1.46um the wedge shows a stop band rather than a negative band suggested in the paper. the only difference between my model and the...
retrieve metamaterial edaboard
the attachment is my code. I saw your request yesterday when i tide my email box, sorry for delay. hope we could dicusss on the retrieval together

sorry,here is the attachment
forum negative refraction smith robust edaboard
Thanks! I've solved the problem in CST. the point is that I should deembed the parameters first or use open boundary instead of open add space. THanks a lot!
retrieve metamaterials matlab
Hi guys,
I'm trying to repeat a work recorded in "Negative index bulk metamaterial at
terahertz frequencies". I used CST to simulate the structure and get the S parameters which keep quite good accordance on magnitude with the data shown in the paper. I made a...
hi guys,
i wanna use periodic boundary but i don't know much about probe detecting. seems that a probe can only detect the signal on one point. but i need the sum of the signal on a surface. i don't know how to do it without set a waveguide port. so i hope somebody could know how to do it. THx!
Hi snkhan,
I have thought about your design but I have some questions not quite clear:
1) if my structrue is an array of SRR, does your boundary condition works for my design? How to use the periodic or unit cell boundary condition for a simple model?
2) why did you divide the whole SRR line...

can srr
Hi snkhan
1) the port's position is determined by the open (add space) boundary condition in the X axis. I know it is strange but don't know how to change it and what's the effect of the changing.
2) I don't understand the boundary condition very well. what i only know is that the...
srr simulation cst
I tried to use CST to simulation a simple SRR structure in GHz. The scale followes the data from fig1 in ref.<Electromagnetic behaviour of left-handed materials>. But when the simulation begins, it always been aborted automatelly with the error:
the current settings will...
