A review on electromagnetic wave absorber based on spoof surface plasmon polariton metamaterials

Spoof surface plasmon polariton (SSPP) represents an artificial electromagnetic mode that extends the properties of optical-frequency surface plasmon polariton into the microwave and terahertz regions. This capability offers a novel platform for designing high-performance microwa...

Time‐Varying Mosaic Metasurface Architecture Enabling Programmable Multi‐Tone Pseudo‑Doppler Spectral Engineering

ABSTRACT The pseudo‐Doppler effect, an artificial frequency shift produced by time‐varying phase modulation of stationary structures, offers a promising route for electromagnetic (EM) wave manipulation. However, existing time‐modulated metasurfaces are predominantly spatially uni...
