A 3D shape with all straight edges and flat faces is a polyhedron. Other 3D shapes with least one curved surface are not polyhedra. A 3D shape with regular polygonal faces, meeting at equal angles, is ...
Abstract: The power bandwidth of Fabry-Pérot-cavity antennas comprised of a thin partially-reflective-surface (PRS) above a perfectly conducting ground plane, based on its ...
Abstract: In this paper, it is shown that by arranging the elements of a beam-scanning planar antenna array in a triangular pattern rather than a rectangular pattern, the number of elements needed in ...
