Enhanced High Dimensionality and the Information Processing Capacity in Interfered Spin Wave‐Based Reservoir Computing, Achieved With Eight Detectors

Advanced Electronic Materials, EarlyView.
Physical reservoir computing (PRC) based on spin wave interference has demonstrated high computational performance, yet room for improvement remains. In this study, we fabricated this concept PRC with eight detectors and evaluated the impact of the number of detectors using a chaotic time series prediction task.

Ultra-Wideband Bandpass Filter using Microstrip-Coplanar Waveguide (CPW) Structure

International Journal of Computer Applications, 2016
In this paper, an ultra-wideband (UWB) bandpass filter (BPF) using Microstrip-coplanar waveguide structure (CPW) is presented. This filter consists of a microstrip line (on top), dielectric substrate (middle) and coplanar waveguide (on conductive ground). The proposed filter has been simulated and measured for UWB bandpass filter.

Surface Charges Guided Quasi‐TEM‐mode Microwave Propagation along Dielectric Nanowire

Advanced Physics Research, EarlyView.
According to Maxwell's equations, a single‐conductor transmission line cannot allow TEM‐mode electromagnetic wave propagation, however, this is based upon the assumption that dielectric material is isolated from the environment. In practice, surface electrostatic charges widely existed in nano‐materials with large surface‐to‐volume ratio.

Nonreciprocal Electro‐Optic Intermodal Scattering With Momentum Engineered RF Waves

Nanophotonics, Volume 15, Issue 12, 25 June 2026.
We demonstrate highly selective nonreciprocal intermodal scattering in thin‐film lithium niobate using slow‐wave RF transmission lines. This electro‐optic momentum engineering approach enables magnet‐free nonreciprocal devices with a single RF input. ABSTRACT Spatiotemporal modulation approaches have been often employed as alternatives for producing ...
