Breaking Optical Transparency and Electromagnetic Performance Trade‐Offs for Transparent Reflective Metasurfaces

Advanced Optical Materials, Volume 14, Issue 40, 27 October 2026.
A theory‐guided magnetoelectric metasurface design breaks the conventional optical transparency and electromagnetic performance trade‐offs. By preserving the electric and magnetic current paths required for efficient reflection through fine‐metal‐line structure, the developed transparent reflective metasurface achieves high optical transparency without

Ultrabroadband, Subvolt Thin‐Film Lithium Niobate Modulators via Codesigned Optical and RF Slow‐Wave Structures

Advanced Photonics Research, Volume 7, Issue 10, October 2026.
In this work, thin‐film lithium niobate Mach–Zehnder modulators are realized using codesigned slow‐light optical waveguides and inductively loaded RF electrodes. This dual slow‐wave engineering optimizes velocity matching, achieving Vπ·L = 0.3 V cm, bandwidths up to 200 GHz, Vπ ≤ 1 V, and short device lengths, offering an efficient solution for high ...

Differential Tissue‐Coupled Powering for Battery‐Free Injectable Electroceuticals

Advanced Science, Volume 13, Issue 60, 28 October 2026.
A thread‐like injectable neural stimulator is powered through differential tissue‐coupled powering (DTCP), which harvests RF‐frequency tissue potentials with an elongated receiver while preserving a injectable cross‐section. The system integrates an ASIC, stimulation electrodes, and a portable transmitter, enabling wireless peripheral nerve stimulation,

Electromagnetic-Thermal Analysis Study Based on HFSS-ANSYS Link [PDF]

, 2011
In this work, rigorous thermal analysis is done for the first time based on the link between Ansoft HFSS and ANSYS. High-frequency results obtained from HFSS including surface loss density and volume loss density are imported into ANSYS.

Bamboo‐Slip‐Inspired Conformal Reconfigurable Metasurfaces

Advanced Science, Volume 13, Issue 58, 19 October 2026.
Bamboo‐slip‐inspired conformal reconfigurable metasurface system. The structure is mainly composed of three parts, which are conformal metasurface, pattern reconfigurable antenna, and control components (such as Field Programmable Gate Array (FPGA)). Conformal metasurfaces draw inspiration from the design of ancient Chinese bamboo slips.

Probability-hesitant fuzzy sets and the representation of preference relations

Technological and Economic Development of Economy, 2018
Probability interpretations play an important role in understanding decision makers’ (DMs) behaviour in decision making. In this paper, we extend hesitant fuzzy sets to probability-hesitant fuzzy sets (P-HFSs) to enhance their modeling ability by taking ...

Recent Advances in Microstrip Patch Antenna Optimization: Methods, Design Targets, and Emerging Trends

Applied Research, Volume 5, Issue 5, October 2026.
This systematic review synthesizes recent advances in Microstrip patch antennas (MPAs) optimization research, highlighting key design targets, optimization methodologies, performance trade‐offs, and application trends. The results demonstrate that MPA optimization is an inherently multivariable problem, with trade‐offs among antenna size, impedance ...
