Electromagnetism: Maxwell Equations, Wave Propagation and by Tamer Becherrawy

By Tamer Becherrawy

This e-book bargains with electromagnetic conception and its purposes on the point of a senior-level undergraduate path for technological know-how and engineering. the elemental strategies and mathematical research are truly constructed and the real functions are analyzed. every one bankruptcy includes various difficulties ranging in hassle from uncomplicated functions to not easy. The solutions for the issues are given on the finish of the e-book. a few chapters which open doorways to extra complex issues, resembling wave concept, designated relativity, emission of radiation via fees and antennas, are included.
The fabric of this ebook permits flexibility within the selection of the themes lined. wisdom of uncomplicated calculus (vectors, differential equations and integration) and basic physics is thought. the necessary mathematical recommendations are progressively brought. After an in depth revision of time-independent phenomena in electrostatics and magnetism in vacuum, the electrical and magnetic houses of topic are mentioned. Induction, Maxwell equations and electromagnetic waves, their mirrored image, refraction, interference and diffraction also are studied in a few aspect. 4 extra subject matters are brought: guided waves, relativistic electrodynamics, debris in an electromagnetic box and emission of radiation. an invaluable appendix on arithmetic, devices and actual constants is included.

Example text

It is not valid to add a vector to a pseudo-vector or write the equality of one component of two vectors without having the other components equal. dr requires that UP and the energy in general be true scalars. 8. Electric charges in nature Although matter is neutral on the macroscopic scale, it is comprised of charged and neutral particles. 602 189 2 × 10−19 C. 3). The stable particles, which are the building blocks of matter, are the proton of charge +e, the electron of charge −e, and the neutron (which is neutral as its name indicates).

Let n be the unit vector normal to S. Show that, for any scalar field f and vector field A, we have ∫∫∫V dV ∇f = ∫∫S dS n f , ∫∫∫V dV ∇ × A = ∫∫S dS (n × A). 12 a) Calculate the divergence of the vector fields B = kr and B = rf(r). B). 13 Let f be a function of r = |r|. Verify that Δf(r) = d2f /dr2 + (2/r) (df/dr). Verify that 1/r is a solution of Laplace’s equation Δf = 0. 14 Let f and g be arbitrary scalar fields while A and B are vector fields. Show the following relations: ∇(fg) = f ∇g + g ∇f , ∇×∇ ∇f = 0, ∇× (f∇ ∇g) = 0, ∇.

On the other hand, often the solution is too complicated to be written in terms of known or simple functions. Approximation or numerical methods must be used in such cases. To illustrate the use of Laplace and Poisson’s equations, let us consider a ball of radius R and uniform charge density qv. The potential V verifies Poisson’s equation inside the ball and Laplace’s equation outside the ball. Using the expression of the Laplacian in spherical coordinates and noting that V does not depend on θ and ϕ because of the spherical symmetry, we get the equations q 1 d 2 dV [r ] = − v (for r < R ) εo dr r 2 dr and 1 d 2 dV [r ] = 0 (for r > R ).
