摘要
缩比模拟是研究电磁效应的有效方法。微波波段的大尺度缩比需要毫米波甚至太赫兹波段的辐射源,但实现技术复杂。提出使用光波模拟电磁散射效应的方法,并从光波的本质、光与无线电波的反射、绕射和干涉效应等方面研究分析了光波与无线电波的物理相似性; 从长相干光源、波束赋形、偏振方式实现、宽视角接收、散射体电磁效应模拟等方面分析论证了光学系统模拟电磁系统散射效应的技术可行性。研究结果对电磁系统特别是微波波段电磁系统的大尺度缩比模拟具有参考意义。
Abstract
The scale model simulation is a valid method for studying the electromagnetic scattering effect. The scale model simulation with large scale factor in microwave frequency range needs the emitter in millimeter wave or terahertz wave frequency range. The simulation method of the electromagnetic scattering effect using optic wave is put forward. The physical similitude between the optic wave and electromagnetic wave is analyzed, including the essence of the optic wave, the reflection, diffraction and interference effect of optic wave and electromagnetic wave. And the technological feasibility of electromagnetic scattering effect simulation using optic system is studied, including the long coherent light source, beam shaping, realization of polarization mode, reception with wide view angle and the scattering effect simulation of the scatters. The research result is referable for the electromagnetic scattering effect simulation with large scale factor.
