Active Metasurface Based DoA Estimation |
A direction of arrival (DoA) estimation method based on amplifier-integrated active metasurface is proposed in this paper. Nonuniformly periodic time modulation on the metasurface reduces the hardware complexity and only partial elements are required for 2-D DoA estimation. |

Battery-Free, ANN-Assisted Microwave Resonator Array for Ice Detection |
This article presents an ice detection system consisting of a battery-free, chip-less wirelessly interrogated resonator array, and an artificial neural network for enhanced detection robustness. The designed array of split-ring resonators was a narrowband frequency-selective structure with a ground plane reflector which shielded resonance from the effect of installation material. |
