Abstract :
The modeling of a GTEM cell which consists of a tapered rectangular waveguide loaded with an eccentric sloping plate conductor is discussed. The fields of the cross section of the uniform structure are derived by transverse resonance diffraction. The local modes approach is applied to the study of the longitudinal field distribution. Results show the structure to be actually overmoded rather than quasi-TEM. Numerical results agree with those in the literature, where available. The treatment is highly accurate and requires no more computer power than that of a desktop computer
