Wideband information in MOM obtained from narrowband data
When solving radiation and/or scattering problems, the Method of Moments can give wideband information by using a Model Based Parameter Estimation technique for the expansion coefficients. The parameters are obtained by computing the values of expansion coefficients and their frequency derivatives at a fixed center frequency. This requires computing the moment matrix and its frequency derivatives. The technique is illustrated for a thin wire scatterer. Piecewise sinusoids are used as expansion functions and point matching is used for testing. The moment matrix and its derivatives can then be computed analytically. Computed results show that depending on the number of derivatives used, accurate results, including resonances, can be obtained over an octave of bandwidth.
