Abstract
A model for modeling electromagnetic response in a conductor and in dielectric, a method of modeling the electromagnetic response in the conductor and dielectric and a program product therefor. Coupled supplies (delayed capacitive-current-controlled current sources or delayed inductance-voltage-controlled voltage sources) are low pass filtered in an electromagnetic model for the particular medium, e.g., a Partial Element Equivalent Circuit (PEEC) model for a conductor or dielectric. Thus, high frequency model instabilities are substantially reduced or eliminated.
Claims36
A method of modeling electromagnetic responses in a particular medium comprising the steps of:
- a) modeling a network of passive elements and coupled power supplies, said coupled supplies providing power responsive to conduction in at least one corresponding coupled passive element;
- and
- b) modeling a low pass filter filtering a corresponding one of said coupled supplies.
A system for modeling electromagnetic responses, said system comprising:
- means for modeling passive circuit elements;
- means for modeling coupled power supplies;
- means for modeling low pass filters;
- and
- means for representing conductors and dielectric as a combination of modeled said passive circuit elements and modeled said coupled power supplies, each of said modeled coupled power supplies being low pass filtered by a corresponding low pass filter.
A computer-readable medium having stored thereon a plurality of instructions, the plurality of instructions including instructions that, when executed by a processor, cause the processor to:
- a) model a network of passive elements and coupled power supplies, said coupled supplies providing power responsive to conduction in at least one corresponding coupled passive element;
- and
- b) low pass filter each of said coupled supplies.
A computer program product for modeling electromagnetic responses, said computer program product comprising a computer usable medium having computer readable program code thereon, said computer readable program code comprising:
- computer readable program code means for modeling passive circuit elements;
- computer readable program code means for modeling coupled power supplies;
- computer readable program code means for modeling low pass filters;
- and
- computer readable program code means for representing conductors and dielectric as a combination of modeled said passive circuit elements and modeled said coupled power supplies, each of said modeled coupled power supplies being low pass filtered.
