Abstract

High numerical aperture(NA) vector diffraction theory is used to analyze a near field optical system using a solid immersion lens (SIL). The amplitude and phase of the transmitted light through the system changes as a function of the air gap height as well as indices of refraction, incident angle, etc. We call these `amplitude apodization' and `phase apodization'. The characteristics of those are done using supergaussian form. The effects of amplitude and phase apodization on irradiance are investigated for various index of refraction and air gap height.
