Optical vortex beams carrying orbit angular momentum have attracted significant attention recently. Perfect vortex beams, characterized by their topological charge-independent intensity profile, have important applicatio...

We propose a radio frequency (RF) and visibly transparent composite metasurface design comprising newly developed transparent multilayer conductive coatings. Detailed experimental and theoretical analysis of the RF/visib...

The paper analyzes frequency-modulated (FM) autodyne short-range radar systems (SRRS) operating at small distances, which are used in both military and civilian applications and require collaboration between radar specia...
