Nonparaxial Tilted Waveobjects Plachenov, Alexandr B. Chamorro Posada, Pedro Kiselev, Aleksei P. Producción Científica Simple closed-form analytical expressions for tilted astigmatic wave beams and wavepackets that are exact solutions of the wave equation are constructed. They are obtained through two different but equivalent derivations, one is based on a complex shift in the Bateman-type solutions, the other employs their Lorentz transformation. Analytic expressions for the propagation invariants: energy, momentum and orbital angular momentum of tilted waveobjects with general astigmatism are presented. The work of Pedro Chamorro-Posada was supported in part by the Spanish Ministerio de Ciencia e Innovación (MCIN), under Grant PID2020-119418GB-I00, in part by the European Union NextGenerationEU under Grant PRTRC17.I1, and in part by the Consejería de Educación, Junta de Castilla y León, through QCAYLE Project. The work of Aleksei P. Kiselev was supported by Russian Science Foundation under Grant 22-11-00338, in obtaining the results of Sections IV and VII. 2024-10-22T21:37:07Z 2024-10-22T21:37:07Z 2023 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Journal of Lightwave Technology, 2023, vol. 41, p. 2212-2224. 0733-8724 https://uvadoc.uva.es/handle/10324/70908 10.1109/JLT.2023.3243217 2212 7 2224 Journal of Lightwave Technology 41 1558-2213 spa https://ieeexplore.ieee.org/document/10040727 info:eu-repo/semantics/openAccess application/pdf IEEE https://uvadoc.uva.es/bitstream/10324/70908/3/18paperTiltedJLT02.pdf.jpg Hispana TEXT http://rightsstatements.org/vocab/CNE/1.0/ UVaDOC.
