Axially-functionally graded materials are/ types of traditional composite materials in which the mechanical and physical properties are gradually varied from one end to the other. They were used ...
Abstract: A dual-circularly polarized (D-CP) low-profile folded reflectarray (FRA) capable of simultaneous two-dimensional (2-D) beam scanning is proposed. The FRA consists of a planar feed embedded ...
Abstract: This letter proposes a new method for controlling the divergence angles of multimode orbital angular momentum (OAM) vortex beams. A geometric framework is established that allows for the ...
