Fundamentals and Applications of Dielectric Ceramics
Prof. Ashish Garg · IIT Kanpur
About
: This is a course on dielectric ceramics which focusses on fundamentals and applications of such materials. Dielectrics are important class of materials which are useful for many applications including sensors, actuators, capacitors etc. This course will stress on understanding their structure, defect chemistry, and theory of both linear as well as nonlinear dielectrics followed by a brief discussion of their applications.
Intended audience: Undergraduate and postgraduate students of engineering and sciences who work in the area of electronic ceramics and dielectrics.
Prerequisites: Basic understanding of physics and materials science fundamentals of crystallography and defects.
