CIET or the Coupled Integral Equation Technique (CIET) has the analytical content of the Mode Matching method with the inclusion of edge conditions, and solution using the Method of Moments. In this technique, a set of coupled integral equations in the tangential electric fields at the gaps of the interfaces are derived and solved by the moment method using basis functions, which include the edge conditions. The dispersion characteristics of the circular waveguide with dielectric disks was computed for the TM01 mode propagation using the CIET technique. This result was validated against numerical simulation through MAFIA and the results obtained using the mode-matching technique and they agree very closely.
