A new architecture for scalable phased array design is presented. A vector summation technique is used in a new feed network in order to reduce the number of tunable phase shifters in the phased array ...

The number of sensors employed in an array affects the array performance, computational load, and cost. Consequently, the minimization of the number of sensors is of great importance in practice.

Quantum physicists unveil most ‘trustworthy’ random-number generator yet Upgraded system produces strings of random bits in a process that is fully traceable.
