Query: Excellent book for beginning graduate students

This book covers many important topics in electromagnetic theory including many areas in Optics, like diffraction,..etc. It fills a gap between the undergrad text books and the more advance graduate EM texts (like Jackson's,.. etc). The materials are easy to follow and understand with no lack of mathematical rigors.Execllent text for beginning graduate students.
