Nonreciprocal Reconfigurable Microwave Optomechanical Circuit [PDF]
AbstractNonreciprocal microwave devices are ubiquitous in radar and radio communication and indispensable in the readout chains of superconducting quantum circuits. Since they commonly rely on ferrite materials requiring large magnetic fields that make them bulky and lossy, there has been significant interest in magnetic-field-free on-chip alternatives,

Compact Dual-Broadband Dual-Polarized Antenna With Additional Ground Platform
A compact dual-polarized antenna element covering the frequency bands of 0.773~1.0405 GHz and 1.69~2.83 GHz is proposed in this paper. The nested scheme is adopted and the performances of the lower- and upper-band element are analyzed, respectively.
