The Effect of Inhomogeneous Background Magnetic Field on the Electromagnetic Response to High-Frequency Gravitational Waves

Abstract

Transverse perturbative photon fluxes (PPFs) generated by an electromagnetic (EM) response system for high-frequency gravitational waves (HFGWs) detection, is a special physical effect related to some properties of HFGWs. Meanwhile, it is also influenced by the background static magnetic field. In this paper, based on the relationship between PPFs and the distribution of a Gaussian Beam with a homogeneous background static magnetic field, we study the distribution of PPFs and the width of positive signal photon fluxes with an inhomogeneous background static magnetic field. Under this condition, the strength of PPFs is enhanced significantly. Furthermore, by adjusting some parameters and an embedded non-coaxial coil in the background magnetic coil, the width of positive-signal photon fluxes would be enlarged greatly.
