Symmetric Galerkin boundary element method for computing the quantum states of the electron in a piecewise-uniform mesoscopic system
Andrea Cagliero, Lyes Rahmouni
The quantum behavior of charge carriers in semiconductor structures is often described in terms of the effective mass Schrödinger equation, neglecting the rapid fluctuations of the…
Semi-analytical calculation of the singular and hypersingular integrals for discrete Helmholtz operators in 2D BEM
Andrea Cagliero
Approximate solutions to elliptic partial differential equations with known kernel can be obtained via the boundary element method (BEM) by discretizing the corresponding boundary…
Symmetry Breaking in UCA-Based Vortex Waves
Andrea Cagliero
In literature, it is often said that a uniform circular array (UCA) composed of a sufficient number of radiating elements is able to generate a vortex wave with arbitrary topologic…
Circularly Symmetric Light Waves: An Overview
Andrea Cagliero
Orbital Angular Momentum (OAM) waves were first recognized as those specific vortex solutions of the paraxial Helmholtz equation for which the orbital contribution to the total ang…
Vortex Waves and Channel Capacity: Hopes and Reality
Rossella Gaffoglio, Andrea Cagliero, Giuseppe Vecchi +1
Several recent contributions have envisioned the possibility of increasing currently exploitable maximum channel capacity of a free space link, both at optical and radio frequencie…
On the Spectral Efficiency Limits of an OAM-based Multiplexing Scheme
Andrea Cagliero, Rossella Gaffoglio
As reported in several recent publications, a spatial multiplexing involving the transmission of orthogonal waves carrying Orbital Angular Momentum (OAM) is unable to provide spect…
OAM multiple transmission using uniform circular arrays: numerical modeling and experimental verification with two digital television signals
Rossella Gaffoglio, Andrea Cagliero, Assunta De Vita +1
In this work we present the outcomes of a radio-frequency OAM transmission between two antenna arrays performed in a real-world context. The analysis is supplemented by deep simula…
A New Approach to the Link Budget Concept for an OAM Communication Link
Andrea Cagliero, Assunta De Vita, Rossella Gaffoglio +1
Following on from the increasing interest for electromagnetic waves carrying Orbital Angular Momentum (OAM), different configurations of antenna systems able to generate such beams…
