Electromagnetic Fields with MATLAB and Scilab programs is designed for a one semester undergraduate course for students of Electrical and Electronics Engineering, and Electronics and Communication Engineering.

A key feature of this book is the extensive use of Matlab and Scilab based examples that illustrates the programs’ powerful capability to solve electromagnetic field problems. The reader can run these programs to verify the results. Matlab programs are written in such a manner that it can run in any Matlab version. There are 25 open source Scilab programs altogether in the text that have been tested under Scilab software version 5.2 or more. Another attractive feature of this book is the inclusion of more than 100 solved problems and 80 two mark questions.
