A Dash of Maxwell’s: A Maxwell’s Equations Primer – Part 6: The Method of Moments

The Method of Moments has become one of the most powerful tools in the RF engineer’s arsenal. In this chapter, we make the transition from theory to practice, first by attempting to compute the characteristics of a “short dipole” by hand, and then by demonstrating that a computer can do that in just a few seconds.

A Dash of Maxwell’s: A Maxwell’s Equations Primer – Part 5: Radiation from a Small Wire Element

It is time to put these equations to work by computing the radiation from a simple structure, a short wire element.

A Dash of Maxwell’s: A Maxwell’s Equations Primer – Part 4: Equations Even a Computer Can Love

In the preceding chapters we have derived Maxwell’s Equations and expressed them in their “integral” and “differential” form. In different ways, both forms lend themselves to a certain intuitive understanding of the nature of electromagnetic fields and waves. In this installment, we will express Maxwell’s Equations in their “computational form,” a form that allows our computers to do the work.

A Dash of Maxwell’s: A Maxwell’s Equations Primer – Part 3: The Difference a Del Makes

In Chapter 2, I introduced Maxwell’s Equations in their “integral form.” Simple in concept, the integral form can be devilishly difficult to work with. To overcome that, scientists and engineers have evolved a number of different ways to look at the problem, including this, the “differential form of the Equations.” The differential form makes use of vector operations.

A Dash of Maxwell’s: A Maxwell’s Equations Primer – Part 2: Why Things Radiate

In this chapter, Dash makes the modifications to Maxwell’s Equations necessary to encompass the “dynamic” case, that is, where magnetic and electric fields are changing.

A Dash of Maxwell’s: A Maxwell’s Equations Primer – Part 1: An Introduction

Maxwell’s Equations are eloquently simple yet excruciatingly complex. These equations just don’t give the scientist or engineer insight; they are literally the answer to everything RF.
