Analysis of Propagation Characteristics of Circular Waveguide Loaded with Dielectric Disks Using Coupled Integral Equation Technique

Coupled Integral Equation Technique (CIET) is presented for the study of propagation characteristics of circular waveguide periodically loaded with dielectric disks operating in TM01d mode. CIET is a combination of Mode Matching Technique (MMT) and Method of Moments. The results are presented for three materials having different dielectric constants and compared with 3D simulation tool CST Studio in terms of simulation time and accuracy.
