Beyond simple tuning, these devices are increasingly utilized in advanced parametric systems, such as compact antennas capable of exhibiting different radiation patterns in transmission and reception [1], as well as nonreciprocal isolating bandpass filters that achieve isolation through spatiotemporal modulation [2]. https://hdl.handle.net/10630/46747 Diodos semiconductores Electrónica - Aparatos e instrumentos Design Challenges in Time‑Varying Circuits Involving Varactor Diode.
