摘要： A transparent stealth structure includes: a first transparent film structure stacked on a front surface of a transparent base, the first transparent film structure causing energy loss of incident electromagnetic waves having a target frequency to change a phase of transmitted electromagnetic waves propagating toward the transparent base; and a second transparent film structure stacked on a back surface of a transparent base, the second transparent film structure reflecting the transmitted electromagnetic waves having passed through the transparent base while adjusting a phase of reflected waves propagating toward the first transparent film structure, wherein the first transparent film structure includes a first front transparent conductive pattern having a first sheet resistance and a second front transparent conductive pattern filling a region, and the second transparent film structure includes a first rear transparent conductive pattern having a third sheet resistance and a second rear transparent conductive pattern filling a region.
