Welcome to E&M
This two course sequence presents a classical approach to electromagnetism. But, unlike many traditional, junior-level presentations, these lectures introduce classical field concepts together with some connections to quantum counterparts. The philosophy of the class holds little back in seeking to build physical models consistent with a modern understanding of electrodynamics.
PHY 339 (1/2 semester) Field Basics
(don't be fooled by the credit hours, this is a focused and challenging course)
I. Source laws and Vector Fields: Electric
Coulomb and Gauss
the calculus of field structure (div/grad/curl)
Potentials Poisson and Laplace
II. Source Laws and Vector Fields ii: Magnets
Relativity
Biot-Savart and Ampere
Field Structure
Vector potentials
III. Time dependence
The discoveries of Faraday
Maxwell's corrections
A wave equation emerges
IV. Interactions with Material - response theory
dielectrics / electrets
magnets and para/dia magnetism
PHY 340 (1 semester) Moving Beyond Basics
I. A review of E&M and advanced solutions methods
(tricks for the advanced physicist)
Separation of Variables
Fourier Series
Methods of images
Methods of inverse negatives
II. The energy and momentum of classical fields
Poynting thm
Work-Energy thm.
Maxwell tensor
III. Returning to E&M waves
Solutions in free space
Solutions in materials: Fresnel
Reflection and waves guided
Dispersion and Absorption
IV. Electromagnetic Radiation and Scattering
The Lorenz Gauge
Retarded solutions of the wave equation
Multipole radiation patterns
Dipole scattering
V. Classical E&M in a quantum world (time permitting)
E&M as a gauge theory
the beginnings of quantum electrodynamics
The Class
The Class is made up of:
1. Lectures on T/TH 12:30 to 1:15,
2. Discussion /quizzes 1:25 - 1:45
3. Weekly Tutorials.
Grades
40% Tutorial
30% In class - quizzes (these work like a single test with a few problems at a time)
30% Final Exam
Office Hours
You can schedule a face-to-face, zoom, webex, phone, meeting at your convenience through email or text. (If you just ask me in the hall I may forget)
Public Safety Announcements
Every effort will be made to accommodate the current COVID crisis. See the syllabus for utilizing this help. Effort will also be made for students that find themselves facing those little problems of life that sometimes make our daily routines hard to follow. Please feel welcomed to discuss issues of safety and accommodation with the instructor.
In this course we take the peculiar approach of presenting the classical sources of classical fields together. Thus, charge and magnetic moment are placed together instead of separate topics as is usually done
