How can i specify media between 2 curve in MATLAB program

Hi
I want to simulate a Spiral antenna in Matlab with FDTD
Does anyone know how I can specify the area between two curves that represent my antenna?
How do i write code ?(just for this section)
first I analysed fields for dielectric layer after that i want to find PEC layer

every body know that ?

Hello sara67,

If you go to my groups website, http://emlab.utep.edu/index.htm, and go under resources and you will find some lectures notes. They explain how to place devices on a grid for FDTD and other various numerical methods.
