Extension of impedance matrix compression method with wavelet transform for 2‐D conducting and dielectric scattering objects due to oblique plane‐wave incidence

The impedance matrix compression (IMC) technique is applied to analyze the square method–of‐moments (MoM) matrix arising from the surface integral equation for 2‐D conducting and dielectric objects with oblique plane‐wave incidence. The induced current components are processed separately by using wavelet basis functions. The comparison between cylinders with circular and square cross section is presented to show the effectiveness of IMC, which depends on the geometry of the object and the wavelet transform matrix. © 2002 Wiley Periodicals, Inc.
