چکیده

A computational tool for application to educational Electromagnetics is presented. Integrating a set of numerical modules, it allows the simulation and demo of several radio wave-propagation scenarios at the Earth surface. The application was developed using MATLAB and includes field interference due to ground reflection, ray-tracing in a stratified atmosphere, sub-refraction mirage effects, single or multiple obstacles and mobile communication urban environments. The final application includes a graphical user interface (GUI) for data input, which is structured in a building-block approach easily expandable to include other features.

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...

Electromagnetic waves a new tool for cellular communications

Distant cells can communicate with each other in a variety of ways. Electrical and chemical mechanisms are two known mechanisms for the establishment of intercellular connections. In recent years, research has shown that many cells influence each other's behavior by sending electromagnetic waves together. The existence of such connections can justify many unknown cellular behaviors. The article...

An Algorithm for Modeling and Interpretation of Seismoelectric Data

Generally speaking, seismoelectric modeling is a prospecting method based on seismic and electromagnetic waves, in which waves generated by a seismic source at the boundary of the two environments generate a relative fluid-solid motion formed as a result of antagonism between the elastic properties of the environment with the saturated fluid. This research has as its objective, a study of the e...

A Study of Bit Condition for Generation Rx -Mode Waves: Interaction of Particles with Z/UH-Mode Waves

Interactions of charge particles with electromagnetic waves have important effects (linear and nonlinear) on the propagation of electromagnetic waves, and it can somewhat play a role in generation of the new mode waves. Besides, the particle energies can play an important role in causing instability in plasma. The values of parallel energy of the particles have been calculated so that they can ...
