Amplifier‐Based Programmable Metasurface for Bidirectional Full Polarization Enhancement

Small Structures, EarlyView.
An amplifier‐based programmable metasurface is proposed to enhance bidirectional propagation of various polarized electromagnetic waves. The metasurface incorporates patch scatterers, reconfigurable phase shifters, and negative resistors to manipulate wave direction and improve wireless communication coverage. The Class‐E reflection amplifier minimizes

Arbitrary Pulse Shaping using Accelerated Interfaces

Small Structures, EarlyView.
This work introduces a novel method for arbitrary pulse shaping using accelerated interfaces. By exploiting nonuniform Doppler shifts, the authors derive exact scattering relations and compute interface trajectories that transform input pulses into desired waveforms.

An Optically Transparent Transmissive Metasurface for User‐Defined Broadband Electromagnetic Illusion Generation

Small Structures, EarlyView.
This work presents a transparent transmissive metasurface (TTM), designed using a conditional generative adversarial network to achieve broadband electromagnetic illusions. The proposed TTM ensures high optical transparency while precisely manipulating electromagnetic waves, demonstrating effectiveness in practical applications such as camouflage ...
