Electromagnetics in retarded time and photon localization

American Journal of Physics, 1997
Maxwell’s equations are presented in retarded time coordinates, source-free solutions are found which are instantaneously localized. The modified Lorentz force law is discussed.

Electromagnetic Interactions and Photon–Electron Cascades

2009
After a brief introduction and the presentation of a list of the fundamental electromagnetic processes we first define frequently used quantities, relations and concepts. We then review the processes that are relevant for the development of electromagnetic (photon–electron) cascades such as bremsstrahlung by electrons, pair production by photons ...

Electromagnetically enhanced two-photon gain and absorption

OSA Annual Meeting, 1993
Recent research has shown that the interaction between an atom and an electromagnetic field can be modified favorably by illuminating the atom by an intense, auxiliary laser field.

Photon-drag experiment and the electromagnetic momentum in matter

Physical Review B, 1986
The photon-drag experiment of Gibson et al. [Proc. R. Soc. London, Ser. A 370, 303 (1980)], operating in the millimeter region, is analyzed and compared with predictions following from the electromagnetic energy-momentum tensors of Minkowski, of Abraham, of Peierls, and of Einstein and Laub.

Electromagnetic wave propagation in photonic crystals and metamaterials

2022
Οι μεγάλη πρόοδος της νανοτεχνολογίας κατά τον 20ο αιώνα οδήγησε σε πολυάριθμες νέες εφαρμογές που σχετίζονται με διάδοση και έλεγχο ηλεκτρομαγνητικών κυμάτων. Επιπλέον, οδήγησε στην επινόηση και δημιουργία σύνθετων τεχνητών δομών/υλικών με οπτικές ιδιότητες που μπορούν να σχεδιαστούν με κατάλληλο σχεδιασμό της γεωμετρίας της δομής.

Electromagnetic Modelling of Dielectric and Metallic Photonic Crystals

2006
In a first part of this paper, it has been shown from numerical results based on a theory of scattering from thin metallic wires that the formulae coming from mathematical studies of homogenization provides a precise estimate of the properties of metallic photonic crystals, even when the wavelength has the same order of magnitude as the period of the ...

Electromagnetic fields and applications for anisotropic / photonic structures

2021
Το πρώτο μέρος αφορά τoν σχεδιασμό κεραίας με σκοπό την εμφύτευση της σε περιβάλλον ανθρώπινου ιστού. Πιο συγκεκριμένα, η κεραία προορίζεται για την ενσωμάτωση της σε εφαρμογές τύπου βηματοδότη, δηλαδή σε εφαρμογές που έχουν ως περιβάλλον την μορφολογία του ανθρώπινου στήθους.
