Paper Abstract

Various efficient methods for computing fields in focal regions are described. The methods are based on the Kirchhoff integral, the Rayleigh-Sommerfeld integrals, the boundary-diffraction-wave integral, or the angular-spectrum representation. Efficient numerical algorithms are obtained from these diffraction integrals by employing local phase and amplitude approximations, asymptotic approximations, and fast-Fourier-transform algorithms. Both ordinary lenses and holographic lenses are considered.
