Abstract: This paper describes a new method for synthesis of a flat-top beam radiation pattern of three-element antenna arrays. Currently, this is the only method that: (1) gives a semi-analytical ...

At relativistic speeds — that is near the speed of light — time moves more slowly, which would mean the electron beam wouldn't have enough time to spread out, keeping the beam focused.

Traditionally, these OAM beams in the radio domain are generated by uniform circular arrays (UCAs), which suffer from their complex structures mostly because of the complex feeding scheme. This ...

The AN/SPY-7 (V)1 antenna will now proceed to final integration with the ASEV combat system at the Production Test Center (PTC-2) in Moorestown in support of full system delivery to Japan. This ...
