This effect is used to focus strain energy at a particular location in a wave guide. Bending waves are excited at one end of a glass beam and focus to a sharp peak at another location of the beam. The excitation is determined from a time reversed spectral element simulation. The focusing of the bending waves in the glass beam is measured using a Laser Doppler vibrometer. Strong focusing was observed. 000015270 540__ $$aText je chráněný podle autorského zákona č. 121/2000 Sb. 000015270 653__ $$a 000015270 7112_ $$a24th International Congress of Theoretical and Applied Mechanics$$cMontreal (CA)$$d2016-08-21 / 2016-08-26$$gICTAM2016 000015270 720__ $$aVan Gemmeren, Valentin 000015270 8560_ $$ffischerc@itam.cas.cz 000015270 8564_ $$s138392$$uhttps://invenio.itam.cas.cz/record/15270/files/TS.SM07-3.06.pdf$$yOriginal version of the author's contribution as presented on CD, page 2224, code TS.SM07-3.06 . 000015270 962__ $$r13812 000015270 980__ $$aPAPER
