Abstract :
A procedure has been described for improving the speed of the classical physical optics method when applied to the analysis of beam waveguides. The procedure is simple and involves the calculation of a set of equivalent currents on an auxiliary plane. It is expected that the procedure can be an alternative to the higher order Gaussian beam analysis often used for analysis of beam waveguides. The computation time is nearly independent of the frequency and especially for lenses the A-PO method proves to be very efficient.
