Abstract :
The method of lines is applied to the Helmholtz equation in cylindrical co-ordinates to analyse cylindrical inhomogeneous propagation structures such as finlines in circular waveguide housings. The numerical results for the frequency dependent propagation characteristics and the dominant mode characteristic impedance for the finline structures are presented.
