Abstract

This paper is to present a model of surface plasmon microscopy (SPM) with radial polarization and numerically examine its far-field imaging performance. More preciously, we analyze the SP distribution on the back focal plane (BFP) of an immersion objective lens and explore how it is focused on the far-field image plane. We show that many of the effects of large angles are eliminated since the image plane is magnified many times with normal NA lens. Specifically, we show that the strong longitude component in focal plane vanishes in image plane and the calculations of transverse component distributions of the two planes are also different. We establish the model which gives the mathematical model on SPM imaging area and shows great potentials in relevant field such as confocal configuration or interferometric SPM.
