E Plane Metal Insert Filter
An E Plane metal insert filter (Figure 1) described in reference[1] was analysed using a modal matching program(RECTGEN). Only the TEm0 rectangular waveguide modes were used in the analysis. Measured transmission curves from reference[1] are shown together with predictions obtained from RECTGEN in Figure2.
