Dual-mode circular resonator (DMCR)-based waveguide filters, introduced in the beginning of the 1970s, 1-6 have well known advantages, compared to traditional waveguide filters. DMCR-based filters allow for two orthogonal TE 111 modes to be employed by each circular cavity, thereby reducing by a factor of two the number of...
