Chapter 1 Forms The dual space The objects that are dual to vectors are 1-forms. A 1-form is a linear transfor- mation from the n-dimensional vector space V to the real numbers. The 1-forms also form a vector space V∗ of dimension n, often called the dual space of the original space V of vectors. If α is a 1-form, then the value of α on a vector v could be written as α(v), but instead. For a more general book on modern geometric methods for physics, I highly recommend The Geometry of Physics by Frankel. The exterior algebra of differential forms can also be applied to usual vectors, producing such quantities as bivectors (which are dual to 2-forms just as how vectors are dual to 1-forms).   Perhaps the book by Ismo V. Lindell ("Differential Forms in Electromagnetics", IEEE Press/Wiley, NJ, ) will be able to change this sad scenario. It seems that the difficulty lies mainly in the fact that a proper understanding of k-forms, as antisymmetric (0,k) tensors in differentiable manifolds, requires the study of technical demanding Reviews: 9. Dr. N. Narayana Rao has designed this compact, one-semester textbook in electromagnetics to fully reflect the evolution of technologies in both electrical and computer engineering. This book’s unique approach begins with Maxwell’s equations for time-varying fields (first in integral and then in differential form), and also introduces waves.

This is a textbook on electromagnetic fields and waves completely based on conceptual understanding of electromagnetics. The text provides operational knowledge and firm grasp of electromagnetic fundamentals aimed toward practical engineering applications by combining fundamental theory and a unique and comprehensive collection of as many as . The electric field intensity E is a 1-form and magnetic flux density B is a 2-form giving you $\nabla\times E=-\dfrac{\partial B}{\partial t}$ and $\nabla \cdot B=0$ The excitation fields,displacement field D and magnetic field intensity H, constitute a 2-form and a 1-form respectively, rendering the remaining Maxwell's Equations. Electromagnetism is fundamental to the whole of electrical and electronic engineering. It provides the basis for understanding the uses of electricity and for the design of the whole spectrum of devices from the largest turbo-alternators to the smallest microcircuits.

For instance, electromagnetic tensor, 8 differential forms, [9][10] [11] The linear wave and heat equation and the nonlinear shallow water equations serve as examples throughout the book. View.

Static Equations and Faraday's Law - The two fundamental equations of electrostatics are shown below. ∇⋅E= total 0 Coulomb's Law in Differential Form - Coulomb's law is the statement that electric charges create diverging electric fields. In differential geometry, the commutator of two derivatives is the curvature tensor -- in general relativity, this is the Riemann tensor, while in gauge theories, it's the field strength tensor. In many theories, e.g. string theory, you get higher-form gauge fields (i.e. two-forms, three-forms . It is based on a Harvard course given by the authors back in the 80's, and it is basically a book on the calculus of differential forms geared towards physical applications: gaussian optics, electrical networks, electrostatics, magnetostatics, Maxwell's equations, thermodynamics are some of the topics discussed in the book in this setting.

DESCHAMPS: ELECTROMAGNETICS AND DIFFERENTIAL FORMS (Section IV-B) and the Kirchhoff approximation (Section IV-C) are presented in terms of differential forms to acquaint the reader with the aspect of differential form equations. It is reasonable to conclude that Gauss’ Law (in either integral or differential form) is fundamental, whereas Coulomb’s Law is merely a consequence of Gauss’ Law.

They obviously constitute an essential tool in expressing the laws of physics. Some of their structures, however (exterior algebra, exterior differential operators, and others), are not widely known or used.

Differential forms have been used to express Maxwell's laws since early in this century, but many of the advantages of forms as a tool for applied electromagnetics have only recently been discovered. Relative to the usual vector analysis treatment, differential forms make elementary electromagnetics clearer, simpler, and more intuitive.

where \({\bf B}\) is magnetic flux density and \({\mathcal S}\) is the enclosing surface. Just as Gauss’s Law for electrostatics has both integral and differential forms, so too does Gauss’ Law for Magnetic Fields.

Here we are interested in the differential form for the same reason. The study of electromagnetics is fundamental to the advancement of communications engineering and information technology to push the frontiers of the ultra-fast and the high bandwidth.

Especially engineers using CAD tools for the electromagnetic design of circuits and antennas need a profound background in analytic concepts of electromagnetics. Early books that popularized the use of differential forms for electromagnetism include the old-school texts by Flanders and the surprisingly fun general relativity textbook by Misner et al., which combined rigorous mathematics with clever and interesting graphical illustrations.
