summary: figuring out electromagnetic wave concept is pivotal within the layout of antennas, microwave circuits, radars, and imaging platforms. Researchers in the back of know-how advances in those and different components have to comprehend either the classical concept of electromagnetics in addition to glossy and rising options of fixing Maxwell's equations. To this finish, the publication presents a graduate-level therapy of chosen analytical and computational tools. The analytical tools comprise the separation of variables, perturbation concept, Green's capabilities, geometrical optics, the geometrical idea of diffraction, actual optics, and the actual idea of diffraction. The numerical innovations comprise mode matching, the strategy of moments, and the finite aspect strategy. The analytical tools supply actual insights which are worthy within the layout approach and the discovery of recent units. The numerical equipment are extra able to treating normal and intricate constructions. jointly, they shape a foundation for contemporary electromagnetic layout. the extent of presentation permits the reader to instantly start utilizing the the way to a few difficulties of reasonable complexity. It additionally offers motives of the underlying theories in order that their features and obstacles should be understood
