An analytic model for the transmission of power between circular cylindrical shells and flat plates attached along a circumference of the shell is developed. The model includes transverse displacements associated with bending waves and in-plane displacements associated with longitudinal and shear waves. Plates internal and external to both semi-infinite and infinite shells are modeled. Examples of power transmission coefficients for different incident wave types in the plate, circumferential mode numbers and frequencies are presented and discussed.
