For ultra-high speed recording, all-optical magnetic recording technology with circularly polarized lights has been studied [1–3]. However, it was difficult to localize circularly polarized light for realizing higher density magnetic recording because of the diffraction limit. Our proposed plasmonic cross antenna can generate the nano-sized circularly polarized light inside the recording media for...
In this paper, FDTD method combined with Overset Grid Generation method is proposed to the analysis of the EM fields around a rotating body. We have previously proposed this numerical approach for a stationary and uniformly moving body. Lorentz transformation is combined to the analysis to comprise with the high relative velocities. The results of the numerical analysis show the modulations of the...
All optical magnetic recording with circularly polarized light has been studied for developing ultra-high speed recording. An asymmetric cross antenna, constituted by two perpendicular dipole antennas of different length, is investigated to generate localized circularly polarization in recording medium from linearly polarized incident light.
Background. The superficial spreading type of gastric carcinoma may originate from either a single cellular clone or from several different clones; this issue remains controversial. Indeed, the p53 gene has been shown to play an important role in gastric carcinogenesis, but there have been only a few reports on the heterogeneity of gastric carcinoma with respect to the p53 gene. Methods. We analyzed...
