RT info:eu-repo/semantics/article T1 Nonparaxial Tilted Waveobjects A1 Plachenov, Alexandr B. A1 Chamorro-Posada, Pedro A1 Kiselev, Aleksei P. AB Simple closed-form analytical expressions for tiltedastigmatic wave beams and wavepackets that are exact solutionsof the wave equation are constructed. They are obtained throughtwo different but equivalent derivations, one is based on a complex shift in the Bateman-type solutions, the other employs theirLorentz transformation. Analytic expressions for the propagationinvariants: energy, momentum and orbital angular momentum oftilted waveobjects with general astigmatism are presented.
