摘要超材料由于具有超常规物理性质而被应用于新型天线罩等电磁功能部件。本工作针对大功率电磁波照射下超材料天线窗/天线罩的非线性效应进行了有限元计算。通过模拟电磁波-热耦合行为,研究连续和脉冲电磁波照射下给定超材料的发热情况及其对超材料透波率的耦合。经过优化,开发了耐受1.7 W/cm²连续电磁波及峰值功率7 W/cm²的超材料微结构,稳态最高温度为145 ℃,大功率照射下透波率劣化2%以内。通过样件实测,经大功率电磁波照射后,超材料平板的透波率劣化在1%以内。

Abstract: Metamaterials have smart properties capable of manipulatting electromagnetic waves, so that metamaterials are recently used in electromagnetic function products such as radome or atenna window. The non-linear effect of metamaterials used in radome or atenna window of high-power microwave was studied by finite element method. The behavior of multi-field coupling for metamaterials under high-power continuous or pulse electromagnetic wave was examined both theoretically and experimentally. After optimal design, metamaterial that were resistant to high-power microwave (with average power density of 1.7 W/cm² for continuous electromagnetic wave or peak power density of 7 W/cm² for pulse electromagnetic wave) were developed. The highest temperature under steady state was 145 ℃, and the degradation of transmission ratio under high-power microwave radiation was under 2%. Metamaterial samples were manufactured and tested. The degradation of transmission ratio after exposed to high-power electromagnetic wave was under 1%.

Key words: metamaterials high-power electromagnetic wave multi-physics coupling finite element simulation
