Electromagnetic waves in conductive pipes

Monte Carlo simulations for scattering of electromagnetic waves from perfectly conductive random rough surfaces.

Numerical calculations of mean scattered intensities by simulation of one-dimensional perfectly conductive random rough surfaces are presented. Results relative to backscattering enhancement and more accurate criteria for the validity of the Kirchhoff approximation are obtained. This method can also be used for assessing perturbative theories and for further experiments.

Conductive Materials Composite Electromagnetic Noise Absorber

INTRODUCTION ELECTROMAGNETIC INTERFERENCE issues can arise anywhere in electronic equipment with unpredictable and troublesome effects. These issues challenge hardware design engineers, and the challenges escalate as today’s electronic equipment becomes both thinner and multifunctional. For example, modern cellular phones are being equipped with high-speed microprocessors, wireless LANs, Blueto...

Universal electromagnetic waves in dielectric

The dielectric susceptibility of a wide class of dielectric materials follows, over extended frequency ranges, a fractional power-law frequency dependence that is called the ‘universal’ response. The electromagnetic fields in such dielectric media are described by fractional differential equations with time derivatives of non-integer order. An exact solution of the fractional equations for a ma...

Electromagnetic Waves in Cavity Design

Understanding electromagnetic wave phenomena is very important to be able to design RF cavities such as for atmospheric microwave plasma torch, microwave vacuum oscillator/amplifier, and charged-particle accelerator. This chapter deals with some electromagnetic wave equations to show applications to develop the analytic design formula for the cavity. For the initial and crude design parameter, ...
