Ultra‐High Isolation Decoupling and Matching Network for mmWave Antennas in Near‐Range FMCW Radars

Microwave and Optical Technology Letters, Volume 68, Issue 10, October 2026.
ABSTRACT A decoupling and matching network (DMN) based on substrate integrated coaxial line technique is proposed to suppress the mutual coupling between a pair of transmitting and receiving antennas operating at 35 GHz. The distorted radiation patterns, typically observed in closely spaced antennas, were improved by introducing carefully designed ...

The Iseult Coil, a Hybrid RF Coil for the First Human Brain Images at 11.7 T: Receive Performance Comparison With a Twin Coil at 7 T

NMR in Biomedicine, Volume 39, Issue 10, October 2026.
Our 8‐Tx/32‐Rx coil is based on two rows of transceiver microstrips intertwined with receive‐only loops. Comparison of the intrinsic SNR at 7 and 11.7 T leads to a 2.2 ratio for the human brain, and 2.75 for a 16‐cm agar sphere, translating into α = 1.5 and 1.95 in the B0α$$ {B}_0^{\alpha } $$‐SNR model, respectively.

A New High‐Pressure Polymorph of MgTe2O5 with a Unique Crystal Structure

European Journal of Inorganic Chemistry, Volume 29, Issue 26, 16 September 2026.
MgTe2O5 synthesized under special high‐pressure/high‐temperature conditions of 8 GPa and 800 °C exhibits a unique crystal structure consisting of fused sechser rings built from pseudooctahedral [TeO5]6– and trigonal‐pyramidal [TeO3]2– units. The single‐crystal structure and temperature‐dependent powder diffraction data are presented.
