Abstract
DOI: 10.1109/TMTT.2023.3337646   IEEEXplore: https://ieeexplore.ieee.org/document/10345702  
Device
Flexible, conformal, multifunctional, time-modulated metasurface or MTMM. 60x60 cells, 263 x 263 x 0.25 mm overall
Spectrum
8-11 GHz
Novelty
Simultaneous control of amplitude, polarization and frequency with independent control of orthogonal polarization. Polarization control is useful for harmonic spectrum conversion. Cylindrical time-modulated metasurfaces are useful to manipulate radar echo signals to produce false targets at different positions.
Application
Radar countermeasures; future information fields.
Performance
3.2 GHz working bandwidth (32%); up to 60° angular stability; 5.6 W power consumption.
