“…The CIP method was proposed by Yabe [8] and applied for electro- magnetic wave analysis by Okubo [9]. Advantage of CIP method compared with conventional finitedifference time-domain (FDTD) method [10] is superiority of accuracy of scattered wave by target with relatively high material constant from the background medium [11,12].…”

Abstract. Post wall waveguides consist of dielectric or metallic cylinders for microwave around 4GHz were experimentally and numerically investigated. The structure attracts interests for application of transmission circuit for three-dimensionally integrated planar circuit in millimeter wavelength. In straight waveguide with dielectric cylinders, confinement of microwave is poor, when the post wall was composed of a pair of single row of cylinders. The confinement was improved as increase of rows of post wall. In metallic cylinders, microwave was well confined even when a pair of single row of cylinders composed the waveguide. After confirming confinement of the electromagnetic field, Y-shaped branches of post wall waveguide consisted of dielectric cylinders for microwave were similarly investigated for dielectric rods. The confinement was also improved by increase of post wall up to 3 layers. These results are applicable for fundamental design and fabrication of integrated circuit for microwave and millimeter wave.

Abstract:The constrained interpolation profile (CIP) method is proposed in the field of computational fluid dynamics, because this method is less influenced by numerical dispersions and is stable with an arbitrary time step. In this paper, the CIP method is applied to room acoustic problems, in which boundary modeling and spatial/time discretization are specifically examined. First, frequencyindependent and frequency-dependent boundary conditions are introduced and validated with an acoustic tube problem. Second, in one-dimensional and three-dimensional closed sound fields, this paper shows that errors in waveforms and reverberation times using the CIP method are smaller than those using the finite difference time domain method even if the steps for time and space are larger. Third, to deal with complicated shapes, the cubic interpolation with volume/area coordinates (CIVA) method using arbitrary triangular elements is introduced; in two-dimensional sound fields, calculation of the CIVA method is stable even if the quality of triangular elements is low.
