Electromagnetic Spectrum (EMS) operations in contested environments require battlefield assumptions based on mission dependent factors and complex ...

Higher frequencies bring more complexity to every part of the network, from tiny antennas to powerful base station processors ...

Abstract: In this letter, a novel uniplanar dual-band quasi-isotropic antenna is proposed. It consists of two folded dipoles, each with a length of 1.5 wavelengths, operating at their respective ...

Abstract: Traditional leaky wave antennas (LWAs) designed with remaining power absorbed at the end of the waveguide lead either to poor radiation efficiency or to poor aperture efficiency. In this ...

The AR glasses optical waveguide system consists of a display and an optical lens that uses TIR principles to transport light. Light is directed into and out of the lens at certain angles, which is ...
