A holey-structured metamaterial for acoustic deep-subwavelength imaging
For classical waves such as light or sound, diffraction sets a natural limit on how finely the details of an object can be recorded on its image. Recently, various optical superlenses based on the metamaterials concept have shown the possibility of overcoming the diffraction limit1–7. Similar two-dimensional (2D) acoustic hyperlens designs have also been explored8–10. Here we demonstrate a 3D h...
متن کاملHoley Fibers for Low Bending Loss
Recently, broadband-access network has spread out rapidly, and Fiber-To-The-Home (FTTH) has showed a stable growth. Nevertheless, for the prevalence of additional FTTH, the so-called 'last one mile problem', which entails a huge cost for constructing optical fiber networks to end-users, has to be solved. To this end, it is necessary to improve economical efficiency of the products for network a...
متن کاملHoley barrier
Endothelial tight junctions (TJs)* are an important functional part of the blood-brain barrier (BBB). In this issue, Nitta et al. (2003) demonstrate that claudin-5, a transmembrane protein of TJs, is a critical determinant of BBB permeability in mice. Unexpectedly, knockout of claudin-5 did not result in a general breakdown of TJs but in a selective increase in paracellular permeability of smal...
متن کاملAcoustic characterization of low intensity focused ultrasound system through skull
Background/introduction Low Intensity Focused Ultrasound (LIFU) continues to gain traction in the field of non-invasive neuromodulation. Recent in vivo rat studies suggest that LIFU can be used to modulate region-specific brain activity in the motor cortex, leading investigators to conclude that LIFU may be a better alternative to more prominent, and more invasive, mechanisms of neuromodulation...
متن کاملHoley factorizations
Holey factorizations of Kv1,v2,...,vn are a basic building block in the construction of Room frames. In this paper we give some necessary conditions for the existence of holey factorizations and give a complete enumeration for nonisomorphic sets of orthogonal holey factorizations of several special types.
