Electromagnetics mainly deals with EM waves, their origin from Maxwell’s equations and their propagation. But the story of EM waves has to be started from the Electric field, Magnetic field, and their static and time-varying relations. Electromagnetics is revolving around Maxwell’s equations.
For understanding the advanced concepts of Electromagnetics, one has to understand terms related to Electric and Magnetic Fields. Basically, all the study of these fields is summarized in the form of Maxwell’s Equations. And Maxwell’s Equations forms the basis for your advanced EMT study including Plane Waves, Waveguides, Transmission line etc.
This Course basically assembles all the Maxwell’s Equations in EMT. It starts with the set of Maxwell’s Equations for static fields viz. Static Electric and Static Magnetic Fields. For the static fields we assume that fields are not time varying i.e. not function of time. In other words we assume that fields are functions of space coordinates.
But when we move on to time varying cases, few equations need modifications. This course covers each and every detail for such modifications. I have explained why the static case is not equally applicable to the time varying case. How does Faraday’s Law enforce the changes into the Maxwell’s equation indicating conservative nature of electric field?
We all know Ampere’s Law which is one of Maxwell’s Equations. But, for time varying fields this Ampere’s Law is inconsistent. I have explained this inconsistency in detail in both ways, analytically as well as intuitively.
To make Ampere’s Law consistent with the time varying fields, Maxwell introduced a completely different type of current known as “Displacement Current”. This course covers each and every micro-point related to Displacement Current. In conjunction with this Displacement Current, I have also revised our normal current viz. Conduction Current. I have made you clear distinction between them.
And finally after summarizing all the Maxwell’s Equations, I have discussed their Phasor forms. The Phasor representation or Time Harmonic representation of Maxwell’s equations is very much necessary for advanced study of Electromagnetics. Almost all the study including Plane waves, Waveguides, Antennas etc. we use Maxwell’s Equations in their Phasor forms or Time Harmonic form.
Finally, with my long experience of teaching many students, I know that usually, a student finds difficulty in understanding Electromagnetics because of lack of visualizations of all these abstract things. So I have tried to solidify the concepts with the help of 3D illustrations.
Prerequisite for Electromagnetics Maxwell’s Equations Course
In the preparation path of the subject Electromagnetic, Maxwell’s Equations play an inevitable role. But, Maxwell’s Equations are actually the summarization of different Laws and Studies related to Electric and Magnetic Fields including their correlation. Hence, it is mandatory to take this course after a sound understanding of Electric and Magnetic Fields’ concepts. So, I strongly recommend you to master the following courses before purchasing this one.
