Abstract:

The isofrequency contours of a photonic crystal are important for predicting and understanding exotic optical phenomena that are not apparent from high-symmetry band structure visualizations. We demonstrate a method to directly visualize the isofrequency contours of high-quality photonic crystal slabs that show quantitatively good agreement with numerical results throughout the visible spectrum. Our technique relies on resonance-enhanced photon scattering from generic fabrication disorder and surface roughness, so it can be applied to general photonic and plasmonic crystals or even quasi-cryst

Abstract:

We consider isofrequency pairing of geodesic orbits that share the same three orbital frequencies associated with Ωr^, Ωφ^, and Ωω^ in a particular region of parameter space around black string spacetime geometry. We study the effect of a compact extra spatial dimension on the isofrequency pairing of geodesic orbits and show that such orbits would occur in the allowed region when particles move along the black string. We find that the presence of the compact extra dimension leads to an increase in the number of the isofrequency pairing of geodesic orbits. Interestingly we also find that isofre

Dynamic in vivo changes in dorsal cochlear nucleus blood flow during pure-tone stimulation were assessed with intravital microscopy. Subjects were stimulated with 5-, 10-, or 15-kHz pure tones at 70, 80, and 90 dB sound pressure level. Measurements in red blood cell velocity and vessel diameter were made in capillaries overlying the 10-kHz isofrequency band of the dorsal cochlear nucleus. Stimulation with 10 kHz induced intensity-dependent increases in local blood flow in the 10-kHz isofrequency band of the dorsal cochlear nucleus. Stimulation with 5 kHz and 15 kHz, frequencies represented in

Abstract:

Dispersion relations and isofrequency curves are of critical importance for understanding the behavior of waves, including what frequencies can be excited, how the waves will propagate, and how waves in one system will couple to another. Here, we present methods to extract the dispersion relations and isofrequency curves automatically and conveniently, each from a single micromagnetic simulation run. These methods have significant advantages in that they provide a means to obtain rapid insight into spin wave behavior in complex situations where analytic approaches are difficult or impossible.

We describe novel topological phases of isofrequency k-space surfaces in bianisotropic optical materials—tri- and tetrahyperbolic materials—which are induced by the introduction of chirality. This completes the classification of isofrequency topologies for bianisotropic materials, as we showed that all optical materials belong to one of the following topological classes—tetra-, tri-, bi-, mono-, or nonhyperbolic. We showed that phase transitions between these classes occur in the k-space directions with zero group velocity at high k-vectors. This classification is based on the sets of high-k p

The topography of responses to monaural and binaural stimuli was appreciably different.

The interpretation of these isofrequency volumes successfully identified previously unresolved subtle structural features, which controlled the natural fracture system.

Band structures of the photonic crystal slabs play a significant role in manipulating the flow of light and predicting exotic physics in photonics. In this Letter, we show that the key features of photonic band structures can be achieved experimentally by the polarization- and momentum-resolved photoluminescence spectroscopy utilizing the light emission properties of SiN x. The two-dimensional spectra clearly reveal the energy-momentum dispersion of band structures, which is in perfect agreement with the simulation results. The isofrequency contours can be measured easily by adding a bandpass

The results obtained could be useful for flat photonic devices with the function of polarization control.

A design procedure based on the optimum damping frequency of the three-parameter isolator is proposed to construct a passive isotropic multi-strut vibration isolation platform (VIP) with three-parameter isolators.

The inferior colliculus (IC) is highly modulated by descending projections from higher auditory and nonauditory centers. Traditionally, corticofugal fibers were believed to project mainly to the extralemniscal IC regions. However, there is some anatomical evidence suggesting that a substantial number of fibers from the primary auditory cortex (A1) project into the IC central nucleus (ICC) and appear to be tonotopically organized. In this study, we used antidromic stimulation combined with other electrophysiological techniques to further investigate the spatial organization of descending fibers

Abstract:

In this paper presents the results of a study of the behavior of surface plasmon polaritons in the layered structure of VO2–SiO2-graphene-based hyperbolic metasurface under the influence of an external magnetic field before and at the beginning of the phase transition of vanadium dioxide. As a result of calculations, it is shown how the Isofrequency contour of surface plasmons changes taking into account the different direction of the external magnetic field. It is also shown how an external magnetic field affects the direction of static magnetization caused by the inverse Faraday effect. This

Abstract:

Responses of single units and clusters of units to tone burst stimulation were recorded at 100-micron intervals along vertical electrode penetrations through the medial geniculate bodies of eight barbiturate-anesthetized cats. Marking lesions were placed at two or three locations along most penetrations to aid in histological reconstruction of electrode tracks. Best frequencies and suprathreshold-response latencies were studied at each location along a penetration. The ventral nucleus is physiologically characterized as a region containing narrowly tuned, short-latency (less than or equal to 4

Abstract:

The phenomenal success of the cochlear implant (CI) is attributed to its ability to provide sufficient temporal and spectral cues for speech understanding. Unfortunately, the CI is ineffective for those without a functional auditory nerve or an implantable cochlea required for CI implementation. As an alternative, our group developed and implanted in deaf patients a new auditory midbrain implant (AMI) to stimulate the central nucleus of the inferior colliculus (ICC). Although the AMI can provide frequency cues, it appears to insufficiently transmit temporal cues for speech understanding. The t

Abstract:

Without using the magnetostatic approximation, the problem of the propagation of electrical magnetic waves in an arbitrary direction in a tangentially magnetized one-sided metal sized bigyrotropic layer. It is shown that in this problem Maxwell’s equations reduce to differential equation to which the biquadratic characteristic equation corresponds equation with four roots k_x21, –k_x21, k_x22 and –k_x22, describing the distribution of the wave in the cross section layer. A dispersion equation is obtained that describes waves with real values k_x21 and k_x22. Based on this equation, the charact
