论文摘要
我们通过电磁波（EMWS）在观察重力波（GWS）中奠定了理论基础，在没有任何光学近似的情况下进行了完整的电磁分析。为此，通过在Minkowski背景时空中使用GWS的扰动麦克斯韦方程来获得平面EMW的扰动。在使用EMWS的GW检测器中，我们建议测量与EMW接收器的运动独立的电磁不变剂，其扰动是衡量不变的。在EMW发射器上施加物理边界条件，我们对可以在EMW接收器中测量的不变性扰动产生了分析结果。最后，我们用单色平面GWS和EMWS显示了检测器的天线模式。
We lay a theoretical foundation in the observation of gravitational waves (GWs) by electromagnetic waves (EMWs) performing a full electromagnetic analysis without any optical approximation. For that, the perturbation of plane EMWs is obtained by solving the perturbed Maxwell equation with GWs in the Minkowski background spacetime. In a GW detector using the EMWs, we propose to measure the electromagnetic invariants that are independent of the motion of the EMW receiver and whose perturbations are gauge-invariant. Imposing a physical boundary condition at EMW emitters, we have analytic results for the perturbations of invariants that can be measured in the EMW receiver. Finally, we show antenna patterns of the detector with monochromatic plane GWs and EMWs.
