Spectral method for multiple edge diffraction by a flat strip
Hiroshi Shirai,L. B. Felsen +1 more
TL;DR: In this paper, a spectral iteration scheme is employed to analyze time-harmonic and transient scattering of an E- or H-polarized incident plane wave by a perfectly conducting plane strip.
Journal ArticleDOI
Hybrid Ray-Mode Analysis of E-Polarized Plane Wave Diffraction by a Thick Slit
TL;DR: In this paper, a high-frequency asymptotic method has been applied to formulate E-polarized plane wave diffraction by a thick slit, which is regarded as an open-ended parallel plane waveguide cavity, and the excitation of the waveguide modes and their reradiation are derived from a ray-mode conversion technique.
Journal ArticleDOI
Effects of Ear Shape and Head Size on Simulated Head Exposure to a Cellular Phone
Shoji Mochizuki,H. Wakayanagi,T. Hamada,Soichi Watanabe,Masao Taki,Y. Yamanaka,Hiroshi Shirai +6 more
TL;DR: The measurement results have been validated by numerical calculation, and support the use of the specific anthropomorphic mannequin (SAM) standard head model.
Proceedings ArticleDOI
Ray mode coupling analysis of EM wave scattering by a partially filled trough
TL;DR: In this article, a high frequency asymptotic ray technique has been applied to analyze electromagnetic plane wave scattering by a partially filled trough, where the modal description has been retained inside the waveguide region.
Journal ArticleDOI
Kirchhoff Approximation Analysis of Plane Wave Scattering by Conducting Thick Slits
Khanh Nam Nguyen,Hiroshi Shirai +1 more
TL;DR: Kirchhoff approximation (KA) method has been applied for ray-mode conversion to analyze the plane wave scattering by conducting thick slits to validate the accuracy of the proposed formulation in different conditions of slit dimension.
