A reconfigurable frequency-notched UWB antenna with split-ring resonators

, 2010
In this paper, two designs of an ultra-wideband antenna with reconfigurable band notches are presented. The first design is based on several nested complementary split-ring resonators, whereas the second has two identical split-ring resonators ...

Permittivity Sensors Based on Conventional and Complementary Split Ring Resonators

This work presents some considerations for the use of a Split Ring Resonator (SRR) and its dual structure, the Complementary Split Ring Resonator (CSRR), as permittivity sensing elements. The analytical circuit equivalents of both resonators are reviewed

Comparison between complementary split ring resonators and electromagnetic band-gap as EMI reduction structures

, 2010
In this work a comparison between complementary split ring resonators (CSRRs) and Electromagnetic Band-Gaps (EBGs) in terms of EMI filter performance is developed. Results show a similar EMI rejection level in both cases but CSRRs present a significantly

From Shear to Sound: Mechanics–Acoustics Mapping of TPMS Lattices

Advanced Engineering Materials, EarlyView.
Triply periodic minimal surface (TPMS) lattices are mapped across mechanical and acoustic performance, revealing that descriptors validated in compression fail under shear. First‐time comparison with trusses included. A transition from porous to resonance‐driven absorption emerges at 25% density.

Biomass Native Structure Into Functional Carbon‐Based Catalysts for Fenton‐Like Reactions

Advanced Functional Materials, EarlyView.
This study indicates that eight biomasses with 2D flaky and 1D acicular structures influence surface O types, morphology, defects, N doping, sp2 C, and Co nanoparticles loading in three series of carbon, N‐doped carbon, and cobalt/graphitic carbon. This work identifies how these structural factors impact catalytic pathways, enhancing selective electron

Metamaterial Inspired Patch Antenna for ISM Band by Adding Single-Layer Complementary Split Ring Resonators

, 2015
In this work, we propose the design of metamaterial inspired compact circular patch antennas loaded with complementary split-ring resonators (CSRRs) for ISM band operation. CSRRs have been incorporated horizontally inside the dielectric.

Counterion Dependent Side‐Chain Relaxation Stiffens a Chemically Doped Thienothiophene Copolymer

Advanced Functional Materials, EarlyView.
Oxidation of a thienothiophene copolymer, p(g3TT‐T2), via different doping strategies and dopant molecules resulted in materials with similar oxidation levels and a high electrical conductivity of ≈100 S cm−1. However, mechanical properties varied significantly, with sub‐glass transition temperatures and elastic moduli spanning from –44°C to –3°C and ...
