Modeling of Frequency Conversion in a Chain of Coupled Resonators due to Time Change in Permittivity

Abstract

This paper considers the transformation of natural modes of single and coupled dielectric resonators when their material is subject to an abrupt time change in permittivity. Both the transient response and the new steady state regime are described in detail. Possibility of frequency shift is demonstrated. Enhancement of the frequency shift for the coupled modes with odd-odd symmetry in the chain has been shown.
