ELECTROMAGNETIC FIELD DISTRIBUTION IN THE FAR-FIELD OF A PYRAMIDAL HORN ANTENNA

Review of the Air Force Academy, 2023
The analysis of electromagnetic compatibility problems in radio electronic systems also involves the study of the distribution of the electromagnetic field generated by the antenna system of the device in the far-field area. Having a solid critical overview of the current research on the topic as a starting point, this article presents, in a synthetic,

Thermal Damage to the Skin From 5.6 GHz Microwave Exposures in Swine

Bioelectromagnetics, Volume 47, Issue 4, May 2026.
ABSTRACT A study of burn thresholds from superficially penetrating radio‐frequency (RF) energy at 5.6 GHz for swine skin was conducted. The study estimated the thresholds for superficial, partial‐thickness, and full‐thickness burn severities after 20 s of exposure at power densities of 4–8 W/cm2. Biopsies were collected from each burn site at 1, 24, 72,

Analysis of Dendritic Specializations in Two Classes of Kenyon Cells in the Mushroom Body of the Adult Honeybee, Apis mellifera

Journal of Comparative Neurology, Volume 534, Issue 5, May 2026.
Honeybee mushroom bodies (MBs), sites for learning and memory, house two classes of intrinsic neurons: class I and II Kenyon cells (KCs) that form synaptic complexes with boutons of projection neurons (PNs) from primary sensory neuropils. Dendrites of both KC classes were restricted to distinct unimodal MB compartments.

Lithium Intercalation in the Anisotropic Van Der Waals Semiconductor CrSBr

Advanced Functional Materials, Volume 36, Issue 34, 27 April 2026.
We report the lithium intercalation in the layered van der Waals crystal CrSBr, revealing strongly anisotropic ion‐migration dynamics. Optical and electrical characterization of exfoliated CrSBr shows lithium diffusion coefficients that differ by more than an order of magnitude along a‐ and b‐directions, consistent with molecular dynamics simulations ...
