We establish a system of difference-differential equations describing the diffraction of light by two mutually perpendicular supersonic waves. When the two supersonics have intensities of the same order of magnitude, we prove that the integration of these equations is reduced to the integration of t
## Synopsis Referring to our previous paper, we deduce solutions in the form of a series of Bessel functions for the systems of difference-differential equations, appearing there. After giving rigorous relations between the coefficients we are able to give explicit expressions for the intensities
A new hybrid Laplace transform/"nite element method is proposed to solve the dynamic problem of a bimodal ultrasonic motor, which used a piezoelectric beam to drive the rotor. Two modes, longitudinal and #exural, of the piezoelectric beam are simultaneously excited by only one power ampli"er. A set
