Course presentation

Electromagnetic Wave Propagation and Scattering, EI2420

Litterature: Jonsson + Ström Electromagnetic wave propagation and scattering, 2016. (Available at the student book store).

2021 Lectures: References are to chapters in Jonsson + Ström.

20/1 Green’s functions and introduction to integral equations §1 
21/1 Integral representation, bounded domain and exterior domain §2. Cherenkov radiation, (external material)

Please read the corresponding material before the class. The associated homework for Chapter 1 and as far as we come on Chapter 2 (in the book) will be for hand in next week. 

Welcome,

Content and learning outcomes

Course contents

  • integral representations of electromagnetic fields by means of Green's functions to finite and unbounded regions of arbitrary geometry
  • assumptions, estimates and approximations that are used in integral representations of electromagnetic fields
  • to explicitly connect the field to the sources 
  • methods to solve integral equations in some typical cases
  • equivalence principle for currents to represent electromagnetic fields
  • design of and explanation of the approximations to determine the field from a reflector antenna
  • numerical calculation of current distribution, scattering and/or reflection and transmission for typical cases as: wire antenna, reflector, stratified sphere and dipole over a horizontal surface
  • vector spherical harmonics
  • geometrical optics and physical optics
  • the differential cross-section for different objects
  • dipole above a conducting surface
  • the null field method and properties of its T-matrix
  • derivations of the integral equations in time domain from a given time harmonic integral equation to represent transient processes
  • numerical labs with laboratory report.

Intended learning outcomes

On successful completion of the course, the student should be able to solve and treat problems in parts of the field of wave propagation and scattering, as described in course content below.
For higher grades, the student should furthermore be able to, with progression in both completeness and width, solve problems from the whole course content analytically and numerically and be able to justify calculations in writing and explain simulation results.

Preparations before course start

Recommended prerequisites

Mathematical Methods in Physics
Theory of Functions
EI2410 Field Theory for Guided Waves, is recommended
Some acquaintance with numerical softwares, like Matlab

Specific preparations

As a preparation to the first two classes please read Chapter 1 and 2 in the book Jonsson and Ström, Electromagnetic Wave Propagation and Scattering. On the first class the second week tmost of the home-work tasks in chapter 1 and the beginning part of chapter 2 will be due to hand in at the start of the first class that week. An exact list of which problems that will give credits will be published on canvas after the last class the first week. 

Literature

Jonsson, Ström, Electromagnetic Wave Propagation and Scattering.

The book is available at the student book store at KTH. 

Examination and completion

Grading scale

A, B, C, D, E, FX, F

Examination

  • TEN1 - Examination, 7.5 credits, Grading scale: A, B, C, D, E, FX, F

Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.

The examiner may apply another examination format when re-examining individual students.

The section below is not retrieved from the course syllabus:

Each weak there are hand-in tasks that are due on the first class next week. They contribute 1-2 credits towards passing the course.

There are three larger homework-problems that each contribute up to 100 credits towards passing the course.

Three hundred HWP and hand-in task credits corresponds to an E in the final grade of the course, 350 to a D. Higher grades are available from the exam.

 

Collected credits during the weeks, y, are converted into exam-contributing credits B according to the formula:

B=min(25+(y-300)/10,34).

 

Grading criteria/assessment criteria

The exam contains 50 points and 

24=Fx, 25=E, 30=D, 35=C, 40=B, 45=A.

Ethical approach

  • All members of a group are responsible for the group's work.
  • In any assessment, every student shall honestly disclose any help received and sources used.
  • In an oral assessment, every student shall be able to present and answer questions about the entire assignment and solution.
