A Nonstationary Geometry‐Based Model for Channel Characterisation in Vactrains Scenarios Using Leaky Coaxial Cables

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,

Dynamic response analysis of high-speed maglev train

, 2022
Abstract Maglev train is suspended through the surrounding track, which overcomesmany disadvantages caused by the direct contact between the wheel and rail oftraditional vehicles, such as excessive friction. It has the advantages of high speed,comfortable riding, less maintenance, strong climbing ability, and so on.

A Multi‐Objective Optimal Synchronous Modulation Strategy for Three‐Level Converter Through Switching Angle Regulation

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
