In this paper, a photonic structure consisting of an extended 3D network of thin wires is shown to behave like a low density plasma of very heavy charged particles with a plasma frequency in the GHz range.Abstract:
A photonic structure consisting of an extended 3D network of thin wires is shown to behave like a low density plasma of very heavy charged particles with a plasma frequency in the GHz range. We show that the analogy with metallic behaviour in the visible is rather complete, and the picture is confirmed by three independent investigations: analytic theory, computer simulation and experiments on a model structure. The fact that the wires are thin is crucial to the validity of the picture. This new composite dielectric, which has the property of negative below the plasma frequency, opens new possibilities for GHz devices.read more

Extremely Low Frequency Plasmons in Metallic Mesostructures
TL;DR: A mechanism for depression of the plasma frequency into the far infrared or even GHz band is proposed: Periodic structures built of very thin wires dilute the average concentration of electrons and considerably enhance the effective electron mass through self-inductance.

Plasma Losses by Fast Electrons in Thin Films
TL;DR: In this paper, the angle energy distribution of a fast electron losing energy to conduction electrons in a thick metallic foil has been derived assuming that the conduction electron constitute a Fermi-Dirac gas and that the fast electron undergoes only small fractional energy and momentum changes.

A Collective Description of Electron Interactions: II. Collective vs Individual Particle Aspects of the Interactions
TL;DR: In this article, the behavior of the electrons in a dense electron gas is analyzed in terms of their density fluctuations, which are then split into two components, one component associated with the organized oscillation of the system as a whole, the so-called "plasma" oscillation, and the other component representing the random thermal motion of the individual electrons.
