我们通过开发一种基于传输线建模（TLM）方法的新的电磁（EM）仿真方法，对最近报道的波形选择超表面进行了数值模拟。与集成电磁模拟器和电路模拟器的传统方法相反，这种模拟方法允许我们完全可视化元表面周围的电磁场。因此，这证明了即使在相同频率下，波形选择性如何随入射波的脉冲宽度而改变周围场。这种模拟方法有望用于测试其他类型的基于电路的超表面和超材料。
We demonstrate numerical simulations of recently reported waveform-selective metasurfaces by developing a new electromagnetic (EM) simulation method based on the Transmission Line Modeling (TLM) method. As opposed to a conventional method integrating an EM simulator with a circuit simulator, this simulation method allows us to fully visualize electromagnetic fields around the metasurfaces. Therefore, this demonstrates how the waveform selectivity varies the surrounding fields in response to the pulse width of the incoming wave even at the same frequency. This simulation method is expected to be useful for testing other kinds of circuit-based metasurfaces and metamaterials as well.
