TL;DR: The ability of designing and building the complex medium has been dramatically enlarged via the development of various types of metamaterial configuration, rapid design system, and sophisticated fabrication technique as mentioned in this paper.

TL;DR: A stacked patch antenna has been proposed and the effects of a finite ground plane on the total radiation pattern are investigated and it is shown that a truncated ground plane of width approximately one wavelength will produce a 3dB beam width for the patch in contrast to the 90 degrees which occurs for an infinite ground plane.

TL;DR: In this paper, a modified offset parabolic reflector antenna design with easily switchable pencil/fan-beam radiation patterns for X-band tracking, scanning and surveillance microwave radar systems is presented.

TL;DR: The implementation and performance results for holography maps that use a radial scan pattern with a position-dependent velocity profile at the LMT are described.

TL;DR: The Li-particulate blanket design for the International Thermonuclear Experimental Reactor (ITER) is proposed in this article, which uses a dilute suspension of fine solid breeder particles in a carrier gas as the combined coolant and lithium breeder stream.
