Super precision spectral encoding for laser imaging via machine learning by Liu, Yunke

“…In our work, a neural network containing residual units is used to build the model between RGB values of laser images in small blocks and the corresponding laser emission wavelength, is trained, and is used on images containing liquid crystal droplets, to make predictions of emission wavelength in every part of these images.…”

Beam-scanning leaky-wave antennas for 5G and satellite applications by Wei, Shuping

“…Then, a LC-based reconfigurable LWA is proposed for beam steering at a fixed frequency with variation of liquid crystal (LC). It utilizes twenty multi-layered CRLH unit cells with LC to obtain a 11° beam scanning angle at 27.5 GHz with a realized gain of 10 dBi.…”
