Microscopic and Macroscopic Electromagnetic Polarization Forces

Abstract

Dipolar forces and hidden momenta are determined for the perfectly electrically conducting sphere. The original additional-boundary-condition method developed by the principal investigator is made applicable to a wider class of spatially dispersive materials and metamaterials. The speckle patterns and correlation functions are determined for the fields radiated by the incoherent sources of spherical "antennas" like the sun and other stars. It is proven that the most commonly used circuit representation of antennas, namely a frequency dependent resistor in series with a reactance, violates time-domain causality and passivity near antiresonances of the antenna. Using a convenient three-vector formulation of the Landau-Lifshitz equation of motion of charged particles, the velocity and powers as functions of time are derived for an electron moving in a counterpropagating laser beam.
