Analysis of field through apertures by applying transmission line matrix method to electromagnetic topology simulations

Results from finite difference time domain simulation were compared with electromagnetic topology based simulation technique using transmission line matrix method for field penetration through the sub-wavelength apertures. Simulations show that electromagnetic topology technique can be applied for the analysis of electromagnetic fields penetration through apertures. Analysis also shows that the aperture size affects the temporal characteristics and frequency spectral components of the incident pulse. In addition, electromagnetic topology method results a reduction in the calculation grid by this technique results in enhanced simulation speed and less memory utilization.
