In this paper, a lightweight high-efficiency circularly polarized (CP) all-metal antenna design method is presented for satellite industry applications. The proposed antenna is composed of a rectangular waveguide feeder, a high-order mode cavity and a metasurface circular polarizer (MCP). The cavity high-order mode TE440 is directly excited by four...

The high mapping efficiency between various structures and electromagnetic (EM) properties of frequency selective surfaces (FSSs) is the state-of-the-art in the EM community. The most straightforward approaches for beam analysis depend on measurements and conventional EM calculation methods, which are inefficient and time-consuming. Equivalent circ...

Understanding and modeling plasma–surface interactions frame a multi-scale as well as multi-physics problem. Scale-bridging machine learning surface surrogate models have been demonstrated to perceive the fundamental atomic fidelity for the physical vapor deposition of pure metals. However, the immense computational cost of the data-generating simu...

Topological valley-locked edge states have been attracting much attention in terahertz (THz) and optical regimes due to their unique unidirectional backscattering-immune feature. However, these one-dimensional edge transports are essentially not compatible to traditional waveguides or devices. In this work, we propose a THz topological waveguide su...

A novel strategy was adopted to prepare (1 − x)Ba(Ti0.97Ca0.03)O2.97–x(Bi0.51Na0.47)0.94Ba0.06TiO3 (abbreviated as (1 − x)BTC–xBNBT, x = 0.03–0.15) relaxor ferroelectric ceramics by precisely tailoring the phase structure and ferroelectric polarization. Significant enhancements in both polarization and dielectric breakdown strength are successfully...

Silica phosphate glasses strengthened with a calcium oxide modifier and doped with different concentrations (0%, 0.5%, 1%, 1.5 mol%) of praseodymium (Pr3+) were synthesized by a sol–gel method. The absence of sharp peaks in the X-ray diffraction spectra confirms the noncrystallinity of the glasses. Higher doping indicates increasing optical bandgap...

This study proposes a double-layer metasurface which is capable of conducting independent amplitude and phase modulation for transmitting x-polarized waves under y-polarized incidence. The phase modulation is controlled by regulating the opening angle of the middle metal ring. Meanwhile, amplitude modulation is achieved by adjusting the rotation an...

The design of low dielectric-loss epoxy resin (EP) systems plays an important role in the insulation optimization of medium-frequency transformers (MFTs). Due to the diversity of EP and curing agents, the traditional design method inspired by dielectric-loss measurements cannot complete low dielectric-loss EP systems design in plentiful candidate E...
