Independently switched UWB antennas alternate between absorber and reflector states to deliver stable, low-cost radar response control.
Patterned isolated conductive regions block 8-20 GHz radar while passing sub-200 MHz communication signals through camouflage material.
Reflective, absorptive, and replaceable adversarial patterns on wearables disrupt UAV machine vision and reduce human target detection.
Graded W-doped VO2 thin films broaden emissivity modulation across temperature, enabling flexible passive infrared camouflage and IR decoys.
A thin protective polymer coating shields the metasurface from friction while preserving selective infrared emission on curved surfaces.
