An Enhanced Genetic Algorithm for Optimization of Seven-Tube Single-Ring Anti-Resonant Hollow-Core Fiber with Record-Low Loss and Single Mode

Photonics
An enhanced genetic algorithm (EGA) is proposed to optimize our previously reported seven-tube single-ring anti-resonant hollow-core fiber (SR-ARF) with a record-low loss of 4.30 dB/km at 1080 nm.

Low loss three-dimensional metamaterial-based omega-net microwave lens

Engineering and Applied Science Research, 2017
Straight forward design of a three-dimensional microwave lens operating from the X- to K-band is proposed. Two-dimensional Omega-net structures that proved to have a near-zero refractive index with low loss are used as a startup design, and later are ...
