Biography

Pranab Kumar Karmakar is currently pursuing research work principally in the area of modeling of integrated water vapor and liquid water in the ambient atmosphere. He is involved in research and teaching at the post-graduate level at the Institute of Radiophysics and Electronics, University of Calcutta in India. Dr. Karmakar published noteworthy outcomes of his research of tropical locations in different international and national journals of repute. All these are culminated into a book entitled Microwave Propagation and Remote Sensing: Atmospheric Influences with Models and Applications published by CRC Press in 2012.

"Certainly, the information content as well as the presentation of the book makes me interested to have it on my shelf. … The author has provided the necessary background for general readership as well as recent trends to arouse interest in the mind of students of electronics and communication engineering, in general, and microwave engineering, in particular. In addition, the book is going to be an important source of inspiration to researchers in the area of microwave sensing and measurement."
