摘要:

The diffraction of an acoustic wave by a rectangular aperture in a soft plane screen is examined by a method which uses orthogonal functions and Fourier transformations. Numerical results of the plane‐wave transmission coefficients for normal incidence are given forb/a=1∠8 andka=0∠2, where 2aand 2bare the side lengths of the aperture andkis the wavenumber.
