Programmable Chiral Radiation via Spin-Decoupled Metasurface with Integrated Compound Phases. [PDF]
Adv Sci (Weinh)A programmable spin‐decoupled metasurface integrating propagation and geometric phases enables high‐purity chiral radiation with reconfigurable emission direction. Spin‐selective radiators combined with a compound phase decoupling strategy suppress undesired components, while embedded PIN diodes allow real‐time directional control.

Low-Noise Voltage Controlled Oscillator with Coupled Microstrip Lines of Different Lengths
Известия высших учебных заведений России: Радиоэлектроника, 2020 Introduction. Coupled two- or three-wire microstrip lines are often used to reduce a phase noise of voltage-controlled oscillators (VCOs). Unfortunately, the phase noise was not optimized depending on the lengths of a three-wire coupled microstrip lines ...
