  • Self-interference along boundaries between positive and negative refractive index media for 3D displays

    Masahiro Daibo, Tomoya Tabuchi, Prathan Buranasiri,

    Proc. SPIE 11331     2020.03  [Refereed]

    Negative index media have a phase velocity opposite to that of the pointing vector. Therefore, if media having the same absolute value of positive and negative refractive indices are alternately arranged, standing waves are generated along the boundaries of the media because these wavelengths are the same and the directions are opposite. We propose a method of generating a stationary interference fringe that is caused by self-interference with irradiating light from a direction parallel to the positive and negative media boundaries.

  • Reflective wavefront control using random zero refractive index medium

    T. Tabuchi, M. Daibo,

    Proc. SPIE 11331     2020.03  [Refereed]

    Bulletin of University, Institute, etc.  Multiple authorship

    The FDTD simulation is performed with a system in which the front-surface is a concave lens, the inside of bulk is a zero refractive index medium in which positive and negative refractive index cells are randomly arranged, and a reflector is placed over the back-surface plane. In a zero-index medium, an outgoing wavefront is always parallel to the outgoing- surface, is independent of either the incident wavefront or the shape of the incoming-surface. After waiting for a while after entering pulsed light into this structure, the light reflected from the back-surface is focused at the focal point of the concave lens over the front-surface.

  • DC-Bias-Magnetic-Field Dependence of Step Response in an Elliptically Polarized Single-Beam Atomic Magnetometer

    Y. Shoji, S. Khanuengchat, S. Takahashi and M. Daibo

    IEEE 2020 8th International Electrical Engineering Congress (iEECON)     2020.03  [Refereed]

    Bulletin of University, Institute, etc.  Multiple authorship

    A single-beam atomic magnetometer with elliptical polarization is simple in construction because it requires only one laser for both pumping and probing. When a small-signal magnetic field is input into the magnetometer after the DC magnetic field is set to zero, a full-wave cleared waveform is output. This characteristic is appropriate for calibration and measurement of DC magnetic fields, because the bias of such fields affects their sensitivity. In this paper, we examined the step-response waveform when a pulsed magnetic field with various DC magnetic-field biases was applied. The response waveform was measured in the time domain with an oscilloscope. The oscillation frequency did not depend on the step-magnetic-field difference but on the amplitude when changing from an absolute-zero magnetic field to a finite magnetic field. Because the DC magnetic field can be determined by measuring the frequency, the bias magnetic field of the atomic magnetometer can be adjusted to maintain the

  • Modeling and Numerical Simulation for a Spherical Vector-Potential Coil

    S. Lekchaum and M. Daibo

    IEEE Transactions on Applied Superconductivity   30 ( 4 ) 1 - 5   2020.01  [Refereed]

    Bulletin of University, Institute, etc.  Multiple authorship

    We proposed a model for a spherical vector-potential coil and investigated the properties of the coil, including the uniform distribution of the vector potential. We modeled a structure in which thin toroidal coils are superposed along a spherical surface. Rather than arranging the toroidal coils in close contact with each other along the surface of the sphere, the layer spacing of the toroidal coils should be constant so that the projection onto the axis of the sphere is equally spaced. When a current was applied to a toroidal coil, no magnetic field was created outside the toroidal coils; instead, a vector potential was present. When the same current was passed through each toroidal coil, the vector potential in the sphere achieved a uniform distribution by superposition. We presented the results of our numerical simulation of the distribution of the vector potential and the induced voltage when a secondary conductor was passed through the coil.
