Modes of a Double-Baffled, Cylindrical, Coaxial Waveguide

Abstract

There is considerable interest in antenna and transmission line structures that are conformal to curved and cylindrical surfaces. The double-baffled, coaxial transmission line is defined by inner and outer raddii, and an arc length. It is conformal to curved surfaces, particularly structures cylindrical in nature. In this note we derive the TE and TM, axially propagating modes of a double-baffled, coaxial transmission line. First, the characteristic equations that define the cutoff frequencies of each mode are derived, then the electric fields are explicitly expressed. Finally, an example double-baffled, coaxial transmission line geometry is defined for which the lowest TE and TM mode cutoff frequencies are computed and graphs of the normalized field components are presented.
