MULTIRESOLUTION MOMENT METHOD BASED ON THE IMPEDANCE OPERATOR FOR THE ANALYSIS OF PLANAR MICROSTRIP STRUCTURES

摘要

This paper presents an integral equation analysis of planar microstrip circuits. In the developed approach, the Moment Method (MoM) with wavelet expansion is combined to the generalized equivalent circuit (GEC) to characterize microstrip structures. The interest of the (GEC) method is to simplify the implementation of the moment method by the translation of an electromagnetic problem to an electric one with the use of the impedance operator. In the multiresolution moment method (MRMoM-GEC), an excitation on the plane of the circuit is used in conjunction with compactly supported wavelets trial functions. This approach generates a sparse linear system. The application of the Discrete Wavelet Transform (DWT), especially for large structures, allows a significant reduction of the unit time of central processing.
