Abstract
Assuming that propagation constants are linearly related to applied control voltages, the experimental estimation procedure for coupling coefficient and propagation constant differences between guides is proposed theoretically. By dividing control electrodes into suitable lengths given by the estimated coupling coefficient, a complete 3×3 switch can be constructed for a device of an arbitrary length. Control conditions for each switching state are analyzed.Keywords
