20.500.12556/RUL-102397 Isolated detection of elastic waves driven by the momentum of light Electromagnetic momentum carried by light is observable through the mechanical effects radiation pressure exerts on illuminated objects. Momentum conversion from electromagnetic fields to elastic waves within a solid object proceeds through a string of electrodynamic and elastodynamic phenomena, collectively bound by momentum and energy continuity. The details of this conversion predicted by theory have yet to be validated by experiments, as it is difficult to distinguish displacements driven by momentum from those driven by heating due to light absorption. Here, we have measured temporal variations of the surface displacements induced by laser pulses reflected from a solid dielectric mirror. Ab initio modelling of momentum flow describes the transfer of momentum from the electromagnetic field to the dielectric mirror, with subsequent creation/propagation of multicomponent elastic waves. Complete consistency between predictions and absolute measurements of surface displacements offers compelling evidence of elastic transients driven predominantly by the momentum of light. radiation pressure elastic waves linear momentum electrodynamics elastodynamics svetlobni tlak elastični valovi gibalna količina elektrodinamika elastodinamika true false true Angleški jezik Slovenski jezik Članek v reviji 2018-08-27 12:43:43 2018-08-27 12:43:45 2022-08-15 03:41:35 0000-00-00 00:00:00 2018 0 0 11 str. art. 3340 Vol. 9 2018 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 519.6:535(045) 2041-1723 10.1038/s41467-018-05706-3 16198683 RAZ_Pozar_Tomaz_2018.pdf RAZ_Pozar_Tomaz_2018.pdf 1 E3B919DABB3DE5D5141A1F4ABE8BD218 f28bfee6aa0ad00e357d8320afa2ed3cedc41d953a23e8f0a88fdec44e497f53 be420c79-a1bb-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=141385 https://www.nature.com/articles/s41467-018-05706-3 1 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=141386 Fakulteta za strojništvo 0 0 0
