In this paper, we indicated that the rectangular pulse propagation in dispersive material in 1-dimensional model, in this calculation, the CIP method is used. From results, the effectiveness of the CIP method were confirmed. The advantage of the CIP method was also confirmed by comparing with the FDTD method. An extension to 2- 3-dimensional models will be our future works.
This paper proposes a dispersive finite-difference time-domain (FDTD) method to analyse metamaterials for the cloaking structures. These materials are anisotropic and possess radial dependent permittivity and permeability. The Drude dispersion model is used to describe the radial dependent material parameters. In addition, the auxiliary differential equation method is applied to take into account...
The numerical method presented herein attempts to equate the scatterer under test to a prescribed equivalent scatterer by adjusting some geometrical and/or constitutive parameters of the equivalent scatterer to reproduce the given values of plane-wave scattering coefficients of the scatterer under test as a function of the incidence angle. Hence, the equivalence is based on the assumption that two...
In this study, the analysis of the left-handed chiral material is presented. The possibility of the negative phase velocity, negative and positive propagation constants, and basic electromagnetic properties of the mentioned medium are also studied. In the analysis, the characterization of left-handed chiral material is given in detail. Some numerical results are also provided to validate the formulation...
In the present paper the eigensolutions are presented for the double wire medium where the wire grid geometry is different in orthogonal directions. This is the generalization of the material with symmetric wire grid. The asymmetry in grid geometry results in different plasma numbers in the effective medium model of permittivity. The eigensolutions are ordinary and extraordinary waves. There are three...
Sublinear signal propagation delay in VLSI circuits carries a far greater penalty in wire area than is commonly realized. Therefore, the global complexity of VLSI circuits is more layout dependent than previously thought. This effect will be truly pronounced in the emerging wafer scale integration technology. We establish lower bounds on the trade-off between sublinear signalling speed and layout...
