However, when the structure of the unit cells lacks 90-degree rotational symmetry, the two fundamental modes become separated. This phenomenon can be termed modal separation. Research reveals that the cause of modal separation is the alteration of the modal current paths for the two fundamental modes. This discovery provides a novel perspective for designing broadband metasurface antennas. Based on this theory, a broadband circularly polarized metasurface antenna is designed. To successfully excite the two modes that are significantly separated in the frequency domain, a stepped coplanar waveguide (CPW)-feed radiator is devised. The proposed metasurface antenna is fabricated and measured, with dimensions of 0.42λ<sub>L</sub> × 0.42λ<sub>L</sub> × 0.045λ<sub>L</sub> (λ<sub>L</sub> is the wavelength in free space at the lowest operating frequency). The measured results show that the antenna has an impedance bandwidth of 4.2–8.3 GHz (65.6%), a 3 dB axial ratio bandwidth of 5.2–6.8 GHz (26.7%), and a peak gain of 5.83 dBi.</p>","PeriodicalId":72073,"journal":{"name":"Advanced quantum technologies","volume":"8 7","pages":""},"PeriodicalIF":4.4,"publicationDate":"2025-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144646984","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, a novel enhancement is proposed to the QAOA, leveraging the Difference of Convex Algorithm (DCA). This method aims to refine QAOA's performance by facilitating the discovery of optimal parameters through a continuous warm-start approach, as originally introduced by Egger et al.

Here, nonperturbative plasmons are modeled having large-amplitude oscillations that approach the extreme limit set by breakdown in characteristic coherence of collective quantum electron gas oscillations. In contrast, conventional plasmons are small-amplitude oscillations. Controlled excitation of such extreme plasmons modeled here has become realizable now with trends in ultrashort particle bunch compression. Extreme plasmons unleash unparalleled possibilities including access to unprecedented Petavolts per meter fields. In this work, an analytical model of this class of plasmons is developed based on quantum kinetic framework. A controllable extreme plasmon, the surface crunch-in plasmon, is modeled here using a modified independent electron approximation. In this model, various quantum effects such as suppression of electron–electron interactions due to non-classical equilibrium states at trajectory extrema are incorporated by introducing a quantum factor, <span></span><math>\u0000 <semantics>\u0000 <msub>\u0000 <mi>F</mi>\u0000 <mi>Q</mi>\u0000 </msub>\u0000 <annotation>$mathcal {F}_Q$</annotation>\u0000 </semantics></math>.</p>","PeriodicalId":72073,"journal":{"name":"Advanced quantum technologies","volume":"8 6","pages":""},"PeriodicalIF":4.4,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144273423","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
