The new equations include all Maxwell solutions plus new ones, among which one may find time-stable and spatially finite ones with photon-like properties and behavior.13 pages, Latex, final version, no figures, new section on eigen properties of Maxwell stress tensor added, minor corresponding changes in the textClassical PhysicsHigh Energy Physics - Theorytext
