Assignment EE818 4 Solutions 1. Waveguide modes a) A rectangular metallic waveguide has dimensions 2.104 cm by 1.052 cm. What are the cut-off frequencies for the six lowest modes? b) A circular metallic waveguide has a radius of 0.839 cm (thus it has about the same crosssectional area as the waveguide in part a. What are the cut-off frequencies of the six lowest modes? How do the two waveguides compare? Answer: a)...
