The fundamental Gaussian light beam has no reactive power [1]. For the basic full Gaussian wave, the reactive power is infinite. In order to obtain finite reactive power, a full Gaussian wave generated by a distribution of electric current rather than a point source in the complex space is necessary. A class of such extended full-wave generalizations of the fundamental Gaussian beam is obtained [2].
