Polarization Stable Triband Thin Square-Shaped Metamaterial Absorber

International Journal of Antennas and Propagation, 2023
An efficient triband metamaterial absorber is presented for X- and K-band applications. The unit cell is of simple shape. The absorber is fabricated on a thin polyamide, which makes it flexible. The parameters of the designed absorber are optimized.

Introducing the Groundbreaking Design of the First n‐Input AND Gate Using an Optical‐MOSFET With a Revolutionary Structure of Pulse‐Shaped Gates

Advanced Photonics Research, Volume 7, Issue 5, May 2026.
The paper introduces the first logic gate implementation using optical metal–oxide‐semiconductor field‐effect transistor architecture, specifically designing two‐input and three‐input AND gates based on a silicene waveguide with pulse‐shaped gates. The key innovations include: (1) pulse‐shaped gate design.

Inductive twin-strip gratings in incident TE waves

Electronics Letters, 1983
The inductive sides of square loops, or the inductive end caps of the Jerusalem cross, are regarded as segments of a regular strip grating, in order to devise equivalent-circuit models of frequency surfaces. This approximation involves errors, depending on frequency, angle of incidence and the choice of the grating.

Extremely asymmetrical scattering in gratings with varying mean structural parameters [PDF]

, 2002
Extremely asymmetrical scattering (EAS) is an unusual type of Bragg scattering in slanted periodic gratings with the scattered wave (the +1 diffracted order) propagating parallel to the grating boundaries.

Visualized Clinical‐Radiomics Model Based on Non‐Contrast Computed Tomography for Predicting Efficacy of Surufatinib in Hepatic Metastases of Neuroendocrine Neoplasms

Cancer Medicine, Volume 15, Issue 5, May 2026.
NCCT radiomics for surufatinib efficacy prediction in HM‐NENs. ABSTRACT Background Hepatic metastatic neuroendocrine neoplasms (HM‐NENs) have few treatment biomarkers and low survival rates. We created a clinical‐radiomics fusion model based on non‐contrast computed tomography (NCCT) to predict Surufatinib efficacy in HM‐NENs.
