恒定电场中的隐形设计

Invisible design in a constant electric field

传统隐形根据变换光学与坐标变换理论,计算出电导率随着电压的变换函数,使电磁波能够绕过障碍物沿原路径继续传播,达到隐形的目的.本文为满足人们的需要设计在高压与低压下分别隐形的装置,使用COMSOL Multiphysics软件模拟验证.

According to the transformation optics and coordinate transformation theory,thetraditional invisibility calculates the transformation function of conductivity with voltage,sothat the electromagnetic wave can continue to propagate around the obstacle along theoriginal path,achieving the purpose of invisibility.In order to meet the needs of people,thedevices that are invisible under high pressure and low pressure are designed.The simulationis verified by COMSOL Multiphysics software.
