Abstract: In this letter, a wideband high-efficiency circularly polarized transmitarray antenna with linear-to-circular polarization (LP-to-CP) conversion is proposed. The element consists of a ...
Abstract: By removing the position sensors from permanent magnet linear synchronous motors (PMLSMs), sensorless control technology can realize applications of PMLSMs in limited space and dusty ...
