“…However, the smoothing factor selection is blind in the basic GRNN model [27], so it is necessary to select the appropriate intelligent algorithm to optimize it. The bat algorithm is a new bionic intelligent optimization algorithm proposed by Yang in 2010 [28]. The algorithm realizes the search of the population in solution space by simulating the predation behavior of bats.…”

The research on the sustainability evaluation of innovation and entrepreneurship education for clean energy majors in colleges and universities can not only cultivate more and better innovative and entrepreneurial talents for the development of sustainable energy but also provide a reference for the sustainable development of innovation and entrepreneurship education for other majors. To achieve systematic and comprehensive scientific evaluation, this paper proposes an evaluation model based on SPA-VFS and Chaos bat algorithm to optimize GRNN. Firstly, the sustainability evaluation index system of innovation and entrepreneurship education for clean energy major in colleges and universities is constructed from the four aspects of the environment, investment, process, and results, and the meaning of each evaluation index is explained; Then, combined with variable fuzzy set evaluation theory (VFS) and set pair analysis theory (SPA), the classical evaluation model based on SPA-VFS is constructed, and the entropy weight method and rank method are coupled to obtain the index weight. The basic bat algorithm is improved by using Tent chaotic mapping, and the chaotic bat algorithm (CBA) is proposed. The generalized regression neural network (GRNN) model is optimized by CBA, and the intelligent evaluation model based on CBA-GRNN is obtained to realize fast real-time calculation; finally, a numerical example is used to verify the scientificity and accuracy of the model proposed in this paper. This study is conducive to a comprehensive evaluation of the sustainability of innovation and entrepreneurship education for clean energy major in colleges and universities, and is conducive to the healthy and sustainable development of innovation and entrepreneurship education for clean energy major in colleges and universities, so as to provide more innovative and entrepreneurial talents for the clean energy industry.

“…Meanwhile, asymmetric structures lead to non-identical performance of two orthogonal polarizations and asymmetric radiation patterns in a way that each polarization was required to be adjusted separately, which increased the design effort. To address these issues, the differential feed proposed in [34], [35] can be adopted to keep the structure symmetrical. More importantly, the differential feed technique can suppress the surface waves [34].…”

This article proposes a wideband differentiallyfed dual-polarized magnetoelectric (ME) dipole for millimeterwave (mm-Wave) applications. Various electric and magnetic characteristic modes of a slotted patch antenna are investigated and utilized effectively to create a stable broadside radiation pattern, covering 5G frequency bands from 24.25 GHz to 40 GHz. To implement this, the lifted ground (LGND) concept is applied to achieve a 57.1% impedance bandwidth for a single antenna element. Additionally, the three resonances of the antenna can be manipulated independently. The use of differential feeding allows more than 36 dB of port-to-port isolation across the entire operating band. The measured gains of the single element and 2×2 array are 8.4 dBi and 13.4 dBi, respectively. Also, the measured results indicate symmetrical E-and H-plane radiation patterns and cross-polarization levels lower than -26 dB. With the favorable electrical performance, compact size, simple structure and low-cost fabrication, the proposed ME dipole is a promising candidate for mm-Wave Antenna-in-Package (AiP) applications.

“…It has been demonstrated that this algorithm is a powerful optimization algorithm, which is superior to the famous standard PSO and GA in terms of accuracy and efficiency [18]- [19]. Since then, the BA has been applied in some engineering applications including the array beamforming [19]- [22] and antenna design [23]. Nevertheless, the applications of this algorithm in antenna field is quite limited.…”
