Frequency-Domain Complementary Operators for Finite-Elements Simulation

Omar M. Ramahi

Page 629.

Abstract:

A new mesh-truncation technique is introduced for the frequency-domain (time-harmonic) solution of open-region radiation problems. The technique is based on the complementary operators method (COM), where two independent solutions are averaged to eliminate first-order boundary reflections. The dual complementariness in the frequency domain is achieved by introducing a discrete-domain operator that achieves the objective of t in the original time-domain development of COM.
