CHARACTERISTIC IMPEDANCE OF WAVEGUIDES USED IN QUASI-TEM MODE

Abstract

The voltage and current of a quasi-TEM mode have been defined as linear functionals of the electric and magnetic field in the two-conductor waveguide. The functional has been chosen so that the error that arises by neglecting the higher modes generated at the junction of two different waveguides is as small as possible. A new definition of the characteristic impedance has been given by means of the so defined voltage and current.
