8 Calculations for Plane Waves Incident upon Various Apertures
In this chapter we present calculations of electromagnetic field components, Poynting vectors, and laser beam intensity profiles and patterns for plane waves incident upon apertures of various shapes using the vector diffraction models presented in Chapter 7.
8.1 Beam Distributions in the Aperture Plane, Circular Aperture
In this section we present computational results of the electric field and light patterns for locations within the aperture plane. Because the points of interest here are located in the plane containing the diffracting element, Hertz Vector Diffraction theory (HVDT) is employed as it is the only model valid in that region whose results will inherently satisfy both ...
