Rayleigh integral
WebTHE RAYLEIGH–SOMMERFELD DIFFRACTION FORMULA The Rayleigh–Sommerfeld diffraction formula uses the Fourier transform of the input field, but Fresnel–Kirchhoff’s integral equation uses the input field directly to find the diffraction field. This appendix shows how the latter is derived from the former WebRayleigh integral calculation. The acronym VERI (visible element Rayleigh integral) will be used henceforth in the paper. Figure 5 Strategy for determining visible elements. INVERSE VERI The inverse VERI is an efficient way to determine the unknown vibration (v„) in Equation (3). The sound pressure at the field points (pf) is measured and the ATM
