IET Microwaves, Antennas &Propagation, Volume 20, Issue 1, January/December 2026.In this paper, a 3D multi‐source GBSM model is proposed for the vacuum tube scenario using LCX. By equating the periodic slots to multiple magnetic dipole antennas, the electric field distribution of LCX is deduced, and the CIR expression is derived. Based on this, the multi‐link spatial‐temporal correlations, including the spatial CCF and temporal ACF,

Development and Challenges of Maglev Transportation
Magnetic levitation (Maglev) transportation and Evacuated Tube Transportation (ETT) represent cutting-edge advancements in high-speed travel. Maglev trains utilize powerful magnets to levitate above the tracks, eliminating friction and allowing for extremely high speeds, and typically have a wide speed range.

IET Power Electronics, Volume 19, Issue 1, January/December 2026.This paper proposes a novel power loss reduction PWM (PLRPWM) strategy for three‐level neutral point clamped inverters. The proposed strategy aims to achieve multi‐objective optimisation by balancing low output harmonics, reduced switching losses and a balanced neutral‐point potential. ABSTRACT Three‐level neutral point clamped (3L‐NPC) converters have
