The defect sizes can vary from parts of a nanometer to hundreds nanometers when nanobubbles are formed in the liquid. The salt ions can be localized both in the bulk phase and close to defects and water–air interfaces, which corresponds to the formation of their bulk and surface hydration structures respectively. Depending on the water : salt molar ratio and the character of the ion hydration, coordination bonds between the ions and closest water molecules are characterized by different effective electronic charges and, hence, different strengths, which is reflected in the vibrational states of the molecules and their infrared absorption spectra in the high-frequency range. Nonempirical simulations carried out for the X(H2O)n clusters (where X = Na+ or Cl– and n ≤ 55) at the DFT-B3LYP/6-31G(d, p) level were used for predicting the absorption spectra of the ionic systems. The results show that the surface and bulk hydration structures of both ions differ in the intensities of spectral signals depending on the frequency subranges, which can be used as indicators of the changing fractions of the bulk and surface hydration structures of the ions particularly reflecting the role of nano-scale defects close to which the ions can be localized in the dynamic structure of the solution.","PeriodicalId":732,"journal":{"name":"Physics of Wave Phenomena","volume":"34 3","pages":"186 - 198"},"PeriodicalIF":1.1,"publicationDate":"2026-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148394791","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}

About 20 years ago, technologies for high-sensitivity spectroscopy in the THz range appeared. The most advanced method is the THz time-domain spectroscopy (THz-TDS). The application of THz spectroscopy in biology has proved to be extremely productive. This is due to the fact that water is an integral component of any biological object, and the THz range has the greatest sensitivity to the intermolecular structure and dynamics of water. It turned out to be possible to study the molecular objects contacting water by analyzing this water. All research in this field can be divided into two areas. The first, to which main attention has been paid, is devoted to the development of THz methods for medical diagnostics. Much has been done in this area, but so far these technologies have not been introduced into widespread medical practice. The second (fundamental) direction is the study of hydrate shells of biomolecules. Fundamentally new data have been obtained in this field, which showed a much greater extent and greater importance of hydrate shells for biological processes than was previously suggested. Both areas logically fit into a new scientific field: THz biophotonics. This review summarizes the main achievements in this line of research. Attention is drawn to the fact that the main target of THz biophotonics is water. It is the spectral manifestations of water in various biological objects that are the main material for analysis in both applied and fundamental research.","PeriodicalId":732,"journal":{"name":"Physics of Wave Phenomena","volume":"34 3","pages":"161 - 174"},"PeriodicalIF":1.1,"publicationDate":"2026-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148394787","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}

The expansion over vector spherical harmonics demonstrates that there is no continuous transition postulated by the limiting absorption principle between physically realizable solutions for dissipative and non-dissipative media. Instead, two solutions change stepwise under switching on/off the medium dissipation. Such solutions’ behaviour explains how the classical theories of radiation in vacuum with electromagnetic fields propagating outward to infinity find agreement with numerous experiments, despite the physical inconsistency of their spatial distributions for the field momentum density. The analysis performed shows that the classical radiation solutions correspond to excitation of electromagnetic fields not in vacuum, as it is commonly thought, but in a weakly absorbing medium. Concerning the nonzero radiant power given by those theories, it appears a consequence of the wrongly defined applicability limits for the obtained solutions and should be corrected by considering the medium dissipation. According to this correction, the true power radiated outward and carried away by the fields from the electrodynamic system appears to be zero.","PeriodicalId":732,"journal":{"name":"Physics of Wave Phenomena","volume":"34 3","pages":"234 - 242"},"PeriodicalIF":1.1,"publicationDate":"2026-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148394901","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}

These phenomena enable highly controlled manipulation of the transmission frequency, laying the groundwork for high-resolution selective filtering functions. In this work, we conduct an in-depth theoretical and numerical study of an innovative acoustic filtering system comprising four asymmetric resonators arranged in series and parallel, and coupled to a main waveguide. Using the transfer matrix method, we analyze the system’s spectral response in detail. Our results highlight the appearance of Fano-type resonances, as well as the phenomenon of acoustic induced transparency (AIT), resulting from destructive and constructive interference between the different resonance paths. The study of the associated quality factors of resonance peaks allows us to quantify the fineness of these resonances and their sensitivity to variations in the geometric parameters of the system. This sensitivity offers great flexibility in frequency control, a key element in the development of compact, efficient, and reconfigurable devices. The observed performance highlights the potential of our system for applications in the fields of medical acoustics, environmental detection, acoustic signal processing, and the development of highly selective smart sensors.","PeriodicalId":732,"journal":{"name":"Physics of Wave Phenomena","volume":"34 2","pages":"130 - 144"},"PeriodicalIF":1.1,"publicationDate":"2026-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147938453","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}
