Effect of electrode resistance for acoustic coupler using quadrature electrode

Abstract

An equivalent circuit analysis including meander electrode resistance is applied to an acoustic coupler which has been proposed using cascaded quadrature wavelength group-type unidirectional structure. Linear circuit composition procedure for multi ports elements is applied in order to explain the meander resistive effect. Cascade-connected ports are prepared for the meander electrode. The experimental results was found to be in good agreement with the improved circuit calculation.
