Optimized Wire Grid Modeling Method for Complex Metal Mesh Fabrics Using Waveguide-Contact Measurement [PDF]

open access: yesSensors
Metal mesh reflective surfaces are widely used in deployable antennas mounted on satellites where lightweight and stowability are required; however, quantitative characterization of reflective performance is difficult due to complex woven/knitted ...

A robust and efficient model for transmission of surface plasmon polaritons onto metal–insulator–metal apertures

open access: yesNew Journal of Physics, 2023
A simple yet accurate model for the transmission of surface plasmon polaritons (SPPs) in a finite metal–insulator–metal (MIM) waveguide to the sides of the apertures is proposed and demonstrated to be more accurate than the available models.

GEORADAR AND RADIOIMPEDANCE DIAGNOSTICS OF THE SELENGA RIVER WATER AREA

open access: yesГеодинамика и тектонофизика, 2022
The relevance of the work is determined by the fact that no radiowave methods have ever been used to study the water areas of rivers and lakes and their geoelectric sections within the Baikal natural territory (BNT) in winter time.

Peano high‐impedance surfaces [PDF]

open access: yesRadio Science, 2005
Following our previous work on metamaterial high‐impedance surfaces made of Hilbert curve inclusions, here we theoretically explore the performance of the high‐impedance surfaces made of another form of space‐filling curve known as the Peano curve. This metamaterial surface, formed by a two‐dimensional periodic arrangement of Peano curve inclusions, is

Mapping a Magnetic Superstorm: March 1989 Geoelectric Hazards and Impacts on United States Power Systems

open access: yesSpace Weather, 2022
A study is made of the relations between geomagnetic and geoelectric field variation, Earth‐surface impedance, and operational interference (“anomalies”) experienced on electric‐power systems across the contiguous United States during the 13–14 March ...
