Abstract: A new method, the multipole theory (MT) method, is presented for calculating the higher order modal characteristics of circular-rectangular coaxial waveguides. The results obtained by the MT method are compared with the exact data reported in the literature. It is shown that the MT method is an accurate and reliable approach for analyzing the higher order modal characteristics of circular-rectangular (C-R) coaxial waveguide.

Key words: circular-rectangular coaxial waveguide, multipole theory, higher order mode
