Mode coupling in circular-cylindrical system and its application to fingerprint resonators

Coupled-mode equations are given in the circular-cylindrical coordinate system for the evaluation of two-dimensional fingerprint resonators. The general form of coupled-mode equations is outlined. The coupling coefficients are found for transverse electric and transverse magnetic modes. The quality value Q is defined, and a numerical evaluation is given. A detailed derivation of the coupled-mode equations is given. >
