Design of a broad band matched termination for an overmoded waveguide

A new geometry of a matched termination using lossy dielectric materials for an overmoded cylindrical waveguide is explored in this present work. The matched termination is designed based on attenuating the microwave using lossy dielectric materials or resistive materials by numerical simulation. The geometry is optimized such that it can be used for a cylindrical waveguide operating on fundamental and other higher order modes. The matched termination is fabricated and tested for its characteristics and the results are validated against simulated values.
