Solving the asymmetric problem is essential for an two-port electromagnetic near-field probing system (ATPS). In this article, advanced forward two-sided correction method (FTACM) has been proposed. Unlike traditional inverse calibration (IACM), it needs two independent excitations created by calibrator; solution process of FTACM and process. The only self-parameter ATPS, including <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">...
In this article, an ungrounded double-loop active differential magnetic field probe (UDAHP) is proposed. The proposed includes two low-noise amplifiers (LNAs) and detection structure, which can ensure a high response. structure also shielded ground plate for suppressing electric coupling improving the common-mode rejection ratio (CMRR). Meanwhile, rotating asymmetric calibration method (RACM) used to correct probing system's asymmetry, improve CMRR, broaden measurement frequency range....
<title>Abstract</title> The integration of multiple functionalities into a single, planar, ultra-compact metasurface has presented significant opportunities for enhancing capacity and performance within compact 5G/6G communication systems. Recent advances in multifunctional metasurfaces have unveiled comprehensive wavefront manipulations utilizing phase, polarization transmission/reflection, coding apertures. Despite these developments, there remains critical need with expanded channel...
A domination coloring of a graph G is proper vertex G, such that each dominates at least one color class (possibly its own class), and dominated by vertex. The minimum number colors among all colorings called the chromatic number, denoted χdd(G). In this paper, we study complexity k-domination problem proving NP-completeness for arbitrary graphs. We give basic results properties χdd(G), including bounds characterization results, further research χdd(G) some special classes graphs, as split...
Researches on the application of sets increasingly attract many scholars, like encryption technique, experimental design, algorithm improving, program artificial intelligence, security image processing and so on. Given that, studies set theory seem more necessary. In this paper, we discuss a kind named anti-average set, which is derived from graceful labellings graphs. Also, some new properties bounds numbers will be shown.

Coding terahertz metasurfaces devices are crucial in scientific research and engineering applications. However, these usually operate at a single frequency point sensitive to polarization. To overcome this limitation, we designed reflective coding metasurface with "0" "1" cells. The exhibits highly efficient, multi-frequency, x-polarized circularly polarized independent characteristics. proposed structure achieves over 97% reflection 180° of phase difference the frequencies 0.7 THz 1.5 THz....
Aiming at nonlinear control system on-line modeling, the effects of training data distribution to performance SVR are analyzed, and a new modeling method based on modified support vector regression (SVR) is proposed. The analyzed results indicate that near added sample should be preserved when updated, which can improve performance; fixed parameters not fit entire process because time-varying, may have substandard output changes in small range. Therefore, three updating criteria proposed,...
Much attention has been paid to the diagonal flips in maximal planar graphs. In this paper, we firstly focus on properties of unflippable edges graphs, and propose concept K <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">4</sub> -embedding. Also, prove that for a graph G with order n(≥ 5), an edge e ϵ E(G) is if only either incident 3-degree vertex or supporting Secondly, give necessary sufficient condition given number flippable edges....
For a simple graph $G$, domination coloring of $G$ is proper vertex such that every dominates at least one color class, and class dominated by vertex. The chromatic number, denoted $χ_{dd}(G)$, minimum number colors among all colorings $G$. In this paper, we discuss the effects some typical operations on as (edge) removal, contraction, edge subdivision, cycle extending.
