Abstract
A general concept of the vectorial spectral analysis of the nonstationary optical fields representing exact solutions to the Maxwell equations is proposed. The method provides the possibility of examining the free-space spatiotemporal evolution of the electromagnetic field in relation to its dependence on the composition of its temporal- and angular-frequency spectra. Particular attention is given to the electromagnetic pulses whose monochromatic components are nondiffracting fields.
