Abstract: Phase-switched screens (PSSs) achieve low detectability for protected targets by intermittently modulating the phase of incident radar waves, altering their scattering characteristics.

Abstract: This paper presents a new kind of space-time-coding (STC)-enabled direction-finding approach for human target localization in smart healthcare environments. The method overcomes the ...

The sides of right-angled triangles are labelled opposite, hypotenuse and adjacent. Trigonometry explores the relationship between sides and angles in right-angled triangles. The hypotenuse is the ...

Over the past decades, engineers have introduced numerous technologies that rely on light and its underlying characteristics. These include photonic and quantum systems that could advance imaging, ...
