Motile Methylobacterium sp. ME121 and non-motile Kaistia sp. 32K were isolated from the same soil sample. Interestingly, ME121 was significantly more motile in the coculture of ME121 and 32K than in the monoculture of ME121. This advanced motility of

A laminated polarizer is analyzed using the finite-difference time-domain method. An antireflection structure based on a subwavelength grating is introduced to achieve high transmission for the transverse-magnetic wave. As a result, a transmissivity

A simplified algorithm for frequency-dependent calculations of a multipole Debye model is developed on the basis of the locally 1-D finite-difference time-domain method (LOD-FDTD) with a fundamental scheme. For absorbing outgoing waves, the convoluti

A simple polarization converter using an L-figured waveguide is analyzed by the imaginary-distance beam-propagation method based on Yee's mesh and the finite-difference time-domain method. It is revealed at a wavelength of 1.55 μm that the polarizat

We develop the FDTD method based on the trapezoidal recursive convolution technique to analyze metallic periodic structures at oblique incidence. The results from the FDTD method agree well with the analytical results.

We develop a frequency-dependent FDTD method to analyze plasmonic devices based on a periodic structure at oblique incidence. The trapezoidal recursive convolution technique is used to treat a dispersive medium. To confirm the validity of the present

We develop a three-dimensional implicit FDTD method based on the locally one-dimensional scheme to analyze periodic structures. Computational time is reduced to 29% of that for the explicit FDTD method with acceptable results being maintained.

Polarization converters using optical nano-waveguides are proposed and investigated numerically. An extinction ratio of more than 15 dB is obtained over a wavelength range of 1.3 μm to 1.7 μm for an embedded air-core waveguide.

[1] An implicit finite difference time domain (FDTD) method is developed to analyze periodic structures at oblique incidence. The split-field technique is applied to the locally one-dimensional (LOD) FDTD method with the periodic boundary condition.

A broadband mirror consisting of a subwavelength grating is analyzed using a locally one-dimensional FDTD method with the periodic boundary condition. A high reflectivity is obtained around wavelengths of 1.4μm and 1.9μm.
