hi prafuldeo
well thanks for your comments but i still dont understand
you said we use periodic boundary conditions for EBG but why not unit cell ? when we use unit cell , it also means our structure is periodic
if you post any simulated model in cst using unit cell boudary condition. that would be great
because i dont know how to excite the structure when using unit cell boundary condtion ? which port to use , waveguide port or plane wave!!
i also dont understand how to interpret the results of unit cell boundary condition
any comments would be great help
regards
