Title:
TRANSPARENT STEALTH STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2021/015327
Kind Code:
A1
Abstract:
An embodiment of the present invention provides a transparent stealth structure having improved visibility and high stealth performance. In this regard, the transparent stealth structure comprises a first transparent film structure and a second transparent film structure. The first transparent film structure is stacked on the front surface of a transparent base, thereby changing the phase of transmitted electromagnetic waves that are moving towards the transparent base while causing an energy loss in electromagnetic waves having a target frequency and being incident thereon. The second transparent film structure is stacked on the rear surface of the transparent base, thereby reflecting the transmitted electromagnetic waves that passed through the transparent base, and controlling the phase of the reflected waves that are reflected towards the first transparent film structure. The first transparent film structure has a first front transparent conductive pattern, which has a first sheet resistance, and a second front transparent conductive pattern, which fills a region where the first front transparent conductive pattern is not formed and has a second sheet resistance greater than the first sheet resistance. The second transparent film structure has a first rear transparent conductive pattern, which has a third sheet resistance, and a second rear transparent conductive pattern, which fills a region where the first rear transparent conductive pattern is not formed and has a fourth sheet resistance greater than the third sheet resistance.
