The Pseudo-Metamaterial Limiter (PML) will use chaotically generated non-linear structures to provide a low insertion loss HPM/EMP limiter. During this effort, a pseudo metamaterial will be researched. The term pseudo is added since the material structure will be formed by the high field electromagnetic wave that the material is intended to interact. The material will act as if it is a metamaterial but it will actually be a material formed by a chaotic process. The material properties will be non-linear to provide the clipping limiting function while the chaotic structure will be formed to couple with HPM/EMP and not couple with the desired small signal to avoid insertion loss. This effort will provide a mechanism for research and understanding pseudo metamaterial structures and provide insight into how to design and optimize these structures high performance limiter applications. This research is expected to be the basis for a new category of inexpensive, self-contained, high performance limiter devices that can be inserted into T/R Modules.
