IMPLEMENTATION OF PASSIVE AND ACTIVE CIRCUIT ELEMENTS IN CYLINDRICAL FINITE-DIFFERENCE TIME-DOMAIN FORMULATION

摘要

The implementation of passive and active linear circuitelements in cylindrical finite-difference time-domain technique(CFDTD) is developed. The updating equations for active elementsuch as a voltage sources and passive elements such as resistors,capacitors and inductors are represented for elements located alongone of the cylindrical coordinate’s independent parameters. Theanalytical solutions for simple circuit configurations are computedand used as a reference to verify and confirm the accuracy of thedeveloped CFDTD formulation and numerical results.
