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. |

Patented Reflectionless Filters Eliminate
Spurs & Intermods
|
Based on a novel, patented filter topology and produced with Mini-Circuits’ industry-leading MMIC design and manufacturing capability, Mini-Circuits’ reflectionless filters are the only commercially available filters that absorb and internally terminate stopband signals rather than reflecting them back up the signal chain. Learn how customers are finding innovative ways to achieve new levels of performance with these revolutionary products and explore over 150 models in stock to see what they can do for your design. |

DFRSWG Slow Wave Structure with Low Loss for 220-GHz Traveling-Wave Tube |
A double flat-roofed sine waveguide (DFRSWG) slow wave structure (SWS) with low loss for 220-GHz traveling-wave tube (TWT) is demonstrated in this letter. Experimental results demonstrate transmission loss of 0.62–0.75 dB/cm in the frequency band of 210–250 GHz. |
