Based on the transformation optics and the concept of complementary media, this letter develops a minimized external invisibility cloak. The proposed cloak composed of a circular sector and two triangle sectors makes this invisible device with a smaller size compared to the complementary cylinder cloak. With the complementary media, the target object to be hidden can be placed at the outside of the...
In this paper we present Tangible humidifier, a simple tangible interface that use emotion metaphor to convey meaning in its interaction design. Our purpose is to take advantage of natural physical metaphor to achieve a heightened legibility and seamless ness of interaction between people and information. At the same time we attempts to make control system invisible with embedded sensors. Advances...
This paper present an efficient technique for the analysis of electromagnetic scattering by a conducting sphere coated with uniaxial anisotropic media. The technique is based on the method of higher order MoM of the surface integral equations. This higher order MoM solution uses the higher order hierarchical basis functions which are based on the modified Legendre polynomials. Numerical examples results...
In this paper, the field decomposition method is used to split the homogeneous Bi-isotropic media into two uncoupled isotropic media instead of direct calculation of complicated Green's function in Bi-isotropic material. The construction of formulation using Poggio-Miller-Change-Harrington-Wu-Tsai (PMCHWT) integral equation for multiple homogenous dielectric objects and the electric field integral...
In this paper, a MoM solution accelerated by the ACA algorithm is presented to analyze electromagnetic wave interactions with complex 3D objects consisting of metallic and uniaxial anisotropic components. The problem has been formulated using the PMCHWT equations for homogeneous anisotropic media and EFIE for conducting surfaces. The ACA algorithm is applied to accelerate the matrixvector multiplication...
