Interaction of electromagnetic fields with media that have time varying properties is of significant interest in different applications. Among such phenomena we should mention propagation of electromagnetic pulses in modulated dielectric waveguides, which finds applications in a range of areas including pulse generation, compression, reshaping and filtering, wavelength conversion and terahertz ...

We demonstrated a construction of negative-index material (NIM) with epsilon(eff)=mu(eff)=-1 employing ferrites only, with no metallic components. Our design of the NIM is motivated by recent coherent potential approximation results and corroborated by exact numerical calculation demonstrating the negative refraction of an electromagnetic beam, with equal incident and refraction angles, as well...

A synopsis exemplifying the employment of Dyson-Schwinger equations in the calculation and explanation of hadron electromagnetic form factors and related phenomena. In particular the contribution: presents the pion form factor computed simultaneously at spacelike and timelike momenta; reports aspects of the evolution of the nucleon and ∆ masses with current-quark mass and the correlation of the...

A method of presenting electromagnetic theory in accordance with the principle of causality is described. Two ‘causal’ equations expressing time-dependent electric and magnetic fields in terms of their causative sources by means of retarded integrals are used as the fundamental electromagnetic equations. Maxwell’s equations are derived from these ‘causal’ equations. Except for the fact that Max...

The wide spread of communication infrastructures brings with it a natural increase of transmission signals in several areas, in particular in urban environments. In this article we introduce a data model to represent the sensible area from an electromagnetic point of view. The risk analysis has to take into account a plethora of information related to several territorial aspects in order to hav...

Abstract The Astrophysical Multimessenger Observatory Network (AMON) aims to connect the world’s leading high-energy and multimessenger observatories. AMON’s objective are evoke discovery of new phenomena, exploit these phenomena as tools for fundamental physics astrophysics, explore archival datasets in search activity. Present projects include distributing low-latency alerts from Neutrino-Ele...
