Cylindrical wave spectrum
WebAbstract: Multiple forward diffraction past an array of many absorbing half-screens whose separation is large compared to wavelength is examined. Starting with the physical optics approximation for half-planes that are equally spaced and of equal height, the field incident on successive edges is represented by a multidimensional Fresnel integral, which is then … WebSection 12.8 reviews the theory of the cylindrical waveguide. Waveguides are extended hollow metal structures of uniform cross section. Traveling waves are contained and …
