Journal ArticleDOI
Theoretical study of the electronic structure of LiX and NaX (X = Rb, Cs) molecules
TL;DR: In this paper, the lowest electronic states of alkali dimers LiX and NaX (X = Rb, Cs) were computed using an ab initio approach with core-potential potentials and full-valence configuration.
Journal ArticleDOI
Broadband High-Gain Antenna for Millimetre-Wave 60-GHz Band
TL;DR: In this paper, a double-layer log-periodic antenna with a reduced size and a limited number of elements is proposed for the 60 GHz band, which achieves a maximum realized gain of 11.8 dBi with an estimated radiation efficiency of 91.2%.
Journal ArticleDOI

TL;DR: This work proposes a novel scheme of broadband chipless RFID tagging that is based on slot coupled tapered slot antenna (TSA) loaded with a set of resonators, referred to as multi-resonators filters (MRF), which can enable development of robust chiplessRFID systems with the promising features of low cost, compact, and lightweight.
Journal ArticleDOI
Ab initio study of Ba+Arn (n = 1–4) clusters: spectroscopic constants and vibrational energy levels
TL;DR: In this paper, the electronic structures of Ba+Arn (n = 1-4) clusters were calculated using [Ba2+] and [Ar] non-empirical core pseudo-potentials complemented by the core polarisation operators for both atoms, which allowed the consideration of core valence correlation effects.
Journal ArticleDOI
Inverse-raised-cosine fibers for next-generation orbital angular momentum systems
Alaaeddine Rjeb,Gianluca Guerra,Khaled Issa,Habib Fathallah,Saleh Chebaane,Mohsen Machhout,Luca Palmieri,Andrea Galtarossa +7 more
TL;DR: In this paper, a few-mode fiber for OAM transmission, based on the inverse-raised cosine (IRC) function, is designed and numerically analyzed in terms of effective index separation among modes, differential group delay, and chromatic dispersion.
