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 ...

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: In multibeam satellite systems, traditional beam layout scheme mainly adopted uniform and regularly spaced circular beams that span the service area, which results in some beams wasting ...

Natural frequencies are important dynamic characteristics of a structure where they are required for the forced vibration analysis and solution of resonant response. Therefore, the exact solution to ...
