Abstract :
A three dimensional finite-difference time-domain (FDTD) representation of three different size GTEM cells is described. Results are shown for a Liao absorbing boundary condition in place of the backwall and absorber, which shows the behavior of an ideal, reflection-free GTEM. The effects of backwall and termination reflections are discussed. Very good agreement is shown between measured and computed electric field frequency response and transverse plane field uniformity. Several conclusions regarding GTEM field behavior are discussed
