Quasistasic modeling of edge fields in planar resonators
Keyword(s):
This paper discusses quasistatic waveguide model for planar resonator placed in multilayer dielectic media, which do not use effective parameters such as effective width of resonator and effective dielectric constant. It allows to use waveguide model in new approach. Edge field is modeled by inclusion of LC-lumped element circuit where values of inductances and capacitances we determined from the solving of electrostatic Laplace equation by the method of moment using the three-dimensional Green function for multilayer dielectric media. A computational experiment showed that the proposed model is effective in modeling planar resonators of complex shape and requires low computational resources.
