Abstract :
The bending losses of the TE0q mode in circular hollow waveguides are obtained with small surface impedance and large admittance based on the exact vector analyses for Maxwell´s equations. Considerable difference is found for a special case between the present result and that obtained previously by using the coupled-mode theory.
