Course content
The objective of the course is to give a solid and basic understanding of the interactions of the electromagnetic (EM) waves for example microwaves, optical waves, x-rays and so on with different materials such as solids and application of such waves in measurements of different properties of the materials. The course is divided into two parts. In the first half, the focus will be on the theoretical background of what are EM waves and their description based on Maxwell's equations. At first, concepts of vectors, Fourier transforms and complex variables will be reviewed. Next, the fundamental laws related to electricity and magnetism such as Coulomb's, Faraday's and Ampere's will be revised to introduce Maxwell's equations. The students will next be introduced to Maxwell’s equations that provide the link between electrical, magnetic and optical properties of matter and how these equations can be used to study the concept of radiation transfer. Explicitly, students will learn to describe the interaction of a plane wave at the plane boundary of two optically dissimilar media and understand the different emerging properties such as reflection, refraction, absorption while from the interaction of a plane wave at a spherical boundary to understand absorption and scattering. Materials such as dielectrics, metals and their interactions with EM waves will be investigated. In the second half, application of EM waves in engineering will be focused. Technologies and method that visualize the interaction of EM waves with materials will be the focus. The cutting-edge tools available in techno plaza will be chosen and the students will be asked to make presentations on their principle and applications. Students will be encouraged to do individual presentations. Students will also be introduced to recent developments in biomedical technologies for studying living things.
