Abstract

In this paper, the concept of analytical continuation is utilized to generate the electric field over a wide frequency band. The problem of interest is TM scattering from a conducting cylinder. A method of moments formulation is utilized to generate information about the current and its derivatives at a specific frequency. This information is utilized to extrapolate the current at other frequencies. The numerical results presented are in good agreement with exact data.
