This paper presents a microstrip variable delay line loaded with liquid crystal varactors in series. The design of the device, including both the theoretical analysis and the fabrication, is presented ...

A design method of reconfigurable single-layer reflective orbital angular momentum (OAM) antenna is presented in this paper. Varactor diodes are utilized to control the phase characteristics of the ...

Lead-halide perovskite nanocrystals (NCs) are promising for fabricating deep-blue (<460 nm) light-emitting diodes (LEDs), but their development is plagued by low electroluminescent performance and ...
