The Plane Wave Spectrum Representation of Electromagnetic Fields

This is a classic text reissued in the joint IEEE/OUP series. It explains and illustrates a powerful technique for use in electromagnetic waves represented by the superposition of plane waves travelling in diverse directions. There is no other self-contained account of this technique available. This reprint includes a new Foreword by Dr. James Wait and an updated bibliography provided by Professor Rod Donnelly.
