Vectorial Structure of a Phase-Flipped Gauss Beam in the Far Field

Abstract

Abstract-Based on the vectorial angular spectrum representation and the method of stationary phase, internal vectorial structures of a phase-flipped Gauss (PFG) beam diffracting in the far field are derived in analytical forms. The energy flux for the TE term, TM term and the whole beam are derived and depicted by numerical examples. Influences of the f parameter on the whole energy flux distributions are analyzed. Discrepancies of the whole energy flux distributions between the paraxial and non-paraxial cases are shown in detailed manners. Furthermore, influences of the f parameter on discrepancies between two cases are also studied.

Simulation Analysis of the Effect of Measured Parameters on the Emissivity Estimation of Calibration Load in Bistatic Reflection Measurement

“…In this section, the differential scattering coefficient and Kirchhoff's law are introduced, which are widely used in the estimation of emissivity [15][16][17]. The estimation of emissivity used in this section is presented as follows.…”

“…The calibration target is used to calibrate the blackbody-calibration load. The emitting wave is Gaussian beam [17], which illuminates in the center of the array perpendicularly. The noise of measurement system is not considered in the simulation process.…”
