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%.
