Propagation and Interaction of Electrostatic and Electromagnetic Waves in Two Stream Free Electron Laser in the Presence of Self-Fields

A relativistic theory for two-stream free electron laser (FEL) with a one-dimensional helical wiggler and ion-channel guiding in the presence of self-fields are presented. A dispersion relation (DR) which includes coupling between the electromagnetic and the electrostatic waves is derived from a fluid model, with all of the relativistic terms related to the transverse wiggler motion. This DR is...

Anisotropic effects of background fields on Born-Infeld electromagnetic waves

We show exact solutions of the Born-Infeld theory for electromagnetic plane waves propagating in the presence of static background fields. The non-linear character of the Born-Infeld equations generates an interaction between the background and the wave that changes the speed of propagation and adds a longitudinal component to the wave. As a consequence, in a magnetic background the ray directi...

Introduction to quantum electromagnetic circuits

The article is a short opinionated review of the quantum treatment of electromagnetic circuits, with no pretension to exhaustiveness. This review, which is an updated and modernized version of a previous set of Les Houches School lecture notes, has three main parts. The first part describes how to construct a Hamiltonian for a general circuit, which can include dissipative elements. The second ...

Non-ionizing electromagnetic waves measurement and monitoring Systems

In this paper, portable and online monitoring systems for non-ionizing EMF measurement, as well as some measurement results in Tehran are discussed. First of all, standards and recommendations related to EMF monitoring, measurement and exposure such as ISIRI No.8567, ICNIRP guideline and ITU-K.83 are reviewed. Then, technical facts and operation of portable device and monitoring station are int...
