Multi-Measurement Correction of Antenna Radiation Responses Obtained in Non-Anechoic Environments
IEEE AccessPrototype measurements, an essential stage in the development of antennas, are normally performed in anechoic chambers. Although capable of providing high-fidelity data (owing to strict control of propagation conditions), such facilities are ...

Structural biology of ferritin nanocages
FEBS Letters, EarlyView.Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Calculation of radiation patterns
Electronics Letters, 1969 The letter proves that two distinct methods of calculating the radiation pattern of a spherical-aperture distribution are mathematically equivalent, i.e. by a spherical-harmonic expansion or by Silver's far-field formula. The merits of each method and their extension to arbitrary-shaped apertures are briefly discussed.

Taguchi Method-Based Synthesis of a Circular Antenna Array for Enhanced IoT Applications
TelecomLinear antenna arrays exhibit radiation patterns that are restricted to a half-space and feature axial radiation, which can be a significant drawback for applications that require omnidirectional coverage. To address this limitation, the synthesis method
