A Compact Resistively Loaded Metamaterial Absorber for 2.4 GHz RF Energy Harvesting With Impedance‐Matched Rectifier Analysis

Advanced Electronic Materials, EarlyView.
A compact resistively loaded metamaterial absorber captures RF energy at 2.4 GHz and directs most of the accepted power to modeled loads. The resonant response is confirmed experimentally for the fabricated absorber, while an impedance‐matched rectifier is evaluated through simulation. The stage‐wise results distinguish absorber, rectifier, and cascade

The effect of standing waves on the attenuation constant for a low‐loss rectangular waveguide

Electronics Letters, 2021
When standing waves are present in a rectangular waveguide, the resistive losses in the walls are not uniformly distributed. This affects the measurement of the attenuation constant.

AFully Micromachined W-Band Coplanar Waveguide to Rectangular Waveguide Transition

, 2007
- A novel fully micromachined coplanar waveguide (CPW) to rectangular waveguide transition is presented in this paper.A metalized probe is adopted to couple the signal from the CPW to the rectangular waveguide through an aperture located at the center of

Self‐Sensing Artificial‐Muscle‐Empowered Humanlike Perception, Interaction, and Positioning

Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.
The proposed self‐sensorized artificial muscle (SSAM) can sense its length change as small as 0.01 mm via a seamlessly integrated multi‐segment induction coil. The SSAM provides accurate length information regardless of its loadings, driving pressure, or muscle design, adequate for robust data‐driven feedback control.

A new rectangular waveguide to coplanar waveguide transition [PDF]

, 1990
A new rectangular waveguide to coplanar waveguide (CPW) transition is described. The transition uses a ridge in one of the broad walls of the waveguide and a nonradiating slot in the opposite wall to split and rotate the electromagnetic fields of the ...

On the Impact of Mechanical Constraint on Band Structure and Photo‐Elastic Effect in Photonic Resonators

Advanced Physics Research, EarlyView.
We computationally investigate the mechanical, electronic, and optical properties of strained GeSn microdisks on silicon substrates. By combining photo‐elasticity, strain‐dependent band‐structure calculations, and optical mode analysis, we study how strain distribution, structural configuration, and temperature affect the electronic band structure and ...

High-efficiency transition between rectangular waveguide and domino plasmonic waveguide

AIP Advances, 2015
In this work, we propose an optimized transition structure to realize smooth and high efficiency conversion from the guided wave supported by a conventional rectangular waveguide (CRW) to the domino plasmon polaritons (DPPs) supported by a domino ...

Left handed rectangular waveguide resonator structures

, 2005
SRRs are constructed as two square-shaped rings, each interrupted by a small gap, as shown in Fig. 1. Embedding small single split resonator elements on a dielectric substrate we obtain negative magnetic permeability for a metamaterials-based ...

A Non‐Volatile Heterogeneous Quantum Dot III‐V/Si DFB Laser With Optical Memristive Behavior

Advanced Physics Research, EarlyView.
A heterogeneous quantum dot III‐V/Si DFB laser stores its own optical state. An ultrathin Al2O3 memristor at the III‐V/Si interface produces non‐volatile wavelength shifts of ∼46 pm and ∼17 dB peak power contrast with zero holding power. Combining coherent light generation and persistent memory in one device opens a path toward neuromorphic photonics ...
