Transformation electromagnetics/optics (TE/TO) has been shown to be a useful technique in designing electromagnetic devices with very unique properties. Here, the concepts of transformation optics for single elements is extended an array “pinwheel” shaped first time. Through full-wave finite element analysis (FEA), it that transformed linear can designed operate identically uniformly spaced dip...

This paper details the design, manufacture, and performance test results of a highly integrated Rx multi-beam active phased array antenna for aerial communications. The proposed comprises three tile-phased antennas consisting antennas, radio frequency, beamforming units. A system revealed achieved gain-to-noise temperature -6 dB/K beam pointing accuracy below 0.4° with four independently operab...

The ability to steer optical beams, crucial to the operation of high-speed optical wireless links may be achieved using optical phased array antennas which have significant potential in this application. The beam formed by the phased array antennas is steered by tuning the relative phase difference between the adjacent antenna elements which may be achieved nonmechanically. In this paper, the c...

The design, construction and basic characteristics of an electronically steered, adaptive phased array antenna for land mobile satellite communications are described. The antenna system includes an array of six microstrip stacked patch antennas, each connected to an RF channel, which include an MMIC Low Noise Amplifier and a commercial silicon monolithic I-Q modulator. A 6-way microstrip combin...

Recent works on focused ultrasound (FUS) have shown great promise for cancer therapy. Researchers are continuously trying to improve system performance, which is resulting in an increased complexity that is more apparent when using multi-element phased array systems. This has led to significant efforts to reduce system size and cost by relying on system integration. Although ideas from other fi...
