This exciting new resource presents a comprehensiveintroduction to the fundamentalsof diffraction of two-dimensional canonicalstructures, including wedge, strip, andtriangular cylinder with different boundaryconditions. Maxwell equations are discussed,along with wave equation and scattered, diffractedand fringe fields. Geometric optics, as well as the geometrictheory of diffraction are explained. MATLAB scripts included for severalwell-known electromagnetic diffraction problems.
