Second-order elastic constants of the materials are used to calculate the average Gruneisen parameter (leftlangle {{{gamma }}_{i}^{j}} rightrangle ), using which the nonlinearity parameter DL has been calculated for different temperatures. The knowledge of DL is used for calculation of acoustic attenuation coefficient per unit frequency square due to phonon–phonon interaction ({{left[ {{{{alpha }} mathord{left/ {vphantom {{{alpha }} {{{f}^{2}}}}} right. kern-0em} {{{f}^{2}}}}} right]}_{{text{L}}}}) and thermoelastic losses ({{left[ {{{{alpha }} mathord{left/ {vphantom {{{alpha }} {{{f}^{2}}}}} right. kern-0em} {{{f}^{2}}}}} right]}_{{{text{th}}}}}). Acoustic attenuations are found to be temperature dependent and increases with it. The magnitude of acoustic attenuation per unit frequency square due to phonon–phonon interactions is greater than that due to thermoelastic losses. The magnitude of acoustic attenuation for the investigated semiconductors is in the order Si < Ge < GaAs < SnTe. It is observed that anharmonicity of the solids which give rise to phonon–phonon interaction is the dominant cause of acoustic attenuation of propagating waves. The acoustic attenuation of propagating waves is found to be proportional to the molecular weights of semiconductors.","PeriodicalId":455,"journal":{"name":"Acoustical Physics","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2024-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141720301","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we demonstrate theoretically and illustrate numerically the possibility of generating an ODSA composed of many diffracted orders. The obtained results show that each diffracted order navigates in space according to its own trajectory and its own velocity. These trajectories are sometimes linear with sinusoidal velocities, sometimes circular with constant velocities and often elliptical with variable velocities. Moreover, the high diffracted orders of this ODSA, which are characterized by a high velocity and a large scanned area, can be controlled by varying the Raman–Nath parameter. The outstanding point is that all these diffracted orders navigate in space with the same sweep frequency despite the diversity of trajectories and velocities. The borrowing of Poincaré and Bloch spheres allows enumerating all these trajectories and presenting them in an elegant and attractive method. This technique can be used in metrology for rotation measurements based on Doppler effect. In addition, we can used it to develop a spatial display allows tracing Lissajous trajectories rather than using an oscilloscope.","PeriodicalId":455,"journal":{"name":"Acoustical Physics","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2024-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141722273","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
