**Project code:****Suggested Prerequisites:****Time investment:**6 months**Portal:Engineering and Technology****School:Engineering, Mathematics****Department:Mechanical Engineering, Electrical Engineering****Stream: Applied mathematics****Level: Graduate**

## Content summary[edit | edit source]

This course is an introduction to metamaterials and composites and how they interact with electromagnetic and elastic waves.

**The content of these notes is based on the lectures given by Prof. Graeme W. Milton (University of Utah) in Spring 2007. **

The author of these Wikiversity notes has, in addition to transcribing the lectures given in class, added to the content of the course by expanding on the details. The notes have subsequently been corrected and modified by several other anonymous authors. However, some errors still remain and the reader is urged to check the calculations before using any of the results.

## Goals[edit | edit source]

This learning project aims to give the student the basic tools needed to start working on metamaterials and waves in composites.
