Part of the Microwave and RF Technology Series book series (MRFT, volume 12)


The electromagnetic field radiated by currents and apertures may be written in a very simple way, as the superposition of plane waves. To do this we introduce the spectral domain, deduced from the spatial domain by 2-D Fourier transformation with respect to the x and y coordinates.
