Abstract :
This paper examines the benefits of grating thickness in regards to enhancing EMI attenuation. Analysis is performed using the FDTD technique using periodic boundary conditions along with new formulations of the CPML absorbing boundary. Furthermore, it is demonstrated that a simple waveguide below cutoff approximation provides accurate results for the normal incident plane wave case.
