for example i want to simulate propagating parallel platewave in a homogenous slab with negative index how can i start to write codes in matlab
The idea is that you use numerical methods to solve those equations. I suggest you look into Finite difference method. It is the easiest methods that i have seen, but coding these algorithms are no easy task. You can look for some codes that are readily available, but I am not sure where to find them. I am currently working on my own code, in matlab, to solve Maxwell equations using the finite difference method. Another option is to use an EM solver that already exists e.g. HFSS, COMSOL, FEKO. I use HFSS a lot!
Fangjing, i don't think mina.nms is to concerned with the electromagnetic parameters. They want to simulate how a parallel plate waveguide, with a DNG substrate, affects a propagating EM wave. HFSS is good for a lot of things, but it breaks down a lot when you use a substrate that is a DNG. That is why it is advantageous to write your own code, that is why i am writing my own code. Mina.nms, is that what you wanted to simulate?
