A rectangular waveguide cavity is made from a piece of copper WR-187 C-band waveguide, with a = 4.755 cm and b = 2.215 cm. The cavity is filled with polyethylene (er = 2.25). If the cavity is required to be resonant at 5 GHz, find the required length, d, for the TE101 and TE102 modes. Ans: 2.20 cm, 4.40 cm.
