Nonprincipal plane scattering of flat plates and pattern control of horn antennas [PDF]

Using the geometrical theory of diffraction, the traditional method of high frequency scattering analysis, the prediction of the radar cross section of a perfectly conducting, flat, rectangular plate is limited to principal planes.

Precise Tailoring 3D Printed In Situ Toughening Low‐k Microwave Transparent Structure via Thiol‐acrylate Chain Transfer Behavior

Advanced Science, EarlyView.
An in situ thiol–acrylate chain transfer‐mediated toughening strategy is introduced for Digital Light Processing (DLP) printing. Benefiting from its excellent printability, a printed gyroid lattice‐filled plate (100 µm wall thickness) achieves 92% transmittance at 10 GHz under a 50° incidence angle following structural optimization. ABSTRACT The unique

Review of the frequency stabilization of TEA CO2 laser oscillators [PDF]

Most applications of TEA CO2 lasers in heterodyne radar systems require that the transmitter has a high degree of frequency stability. This ensures good Doppler resolution and maximizes receiver sensitivity.

Electron Delocalization Induced by 3d–4f Orbital Hybridization of Co─Ce Atom Pairs Toward Enhanced Electromagnetic Wave Attenuation and Antibacterial Performance

Advanced Science, EarlyView.
Co─Ce dual atomic configuration anchored on the surface of NC matrix has been constructed to regulate the local electron structure. The higher occupied states induced by the Co 3d‐Ce 4f orbital hybridization facilitate the formation of polarized electric fields, which in turn strengthens the polarization relaxation and partially repairs the effective ...

A Wood Plasticine With Controlled Phase‐Change Behavior and Malleability for Energy‐Closed‐Loop and Conformally Adaptive Thermal Management

Advanced Science, EarlyView.
A photothermal wood plasticine exhibiting controlled phase‐change behavior and malleable property is developed. The developed wood plasticine can provide all‐day, on‐demand, and low‐loss solar heating for geometrically diverse objects, including thermoelectric generator, human body, and battery, through its controlled crystallization‐melting ...
