Youtube video -- PDF NOTES- download file Physical optics is also the name of an approximation commonly used in optics, electrical engineering and applied physics . In this context, it is an intermediate method between geometric optics , which ignores wave effects, and full wave electromagnetism , which is a precise theory . The word "physical" means that it is more physical than geometric or ray optics and not that it is an exact physical theory. [1] :11–13 This approximation consists of using ray optics to estimate the field on a surface and then integrating that field over the surface to calculate the transmitted or scattered field. This resembles the Born approximation , in that the details of the problem are treated as a perturbati...
