Stealth technology in terms of absorption of electromagnetic waves is a most valuable research area for military purposes. Development of radar absorbing materials (RAM) had been actively researched for a quite long time. In the RAM design, weight, thickn... see more

Transformation optics offers a procedure to design the structures of metamaterials to find the material parameters needed in various applications. However, a methodology of a transformation optics is too complicated. To help users who are beginning to stu... see more

The absorption performance of a locally-reacting acoustic metamaterial under oblique incidence is studied. The metamaterial is composed of a slotted panel, each slit being loaded by an array of Helmholtz resonators. The system is analytically studied usin... see more

I demonstrate that hyperbolic metamaterials may provide the solution to the long-standing prob- lem of the fundamental diffraction limit plaguing conventional microscopy and optical imaging sys- tems. Presented here is the formalism of the theory, classic... see more

 This paper investigates the mutual coupling effects between axial-mode helical antenna arrays. Single-negative (SNG) magnetic metamaterials are developed and used in this work in order to reduce mutual coupling between axial-mode helical antennas us... see more

We study dark solitons, namely density dips with a phase jump across the density minimum, in a one-dimensional, weakly lossy nonlinear acoustic metamaterial, composed of a waveguide featuring a periodic array of side holes. Relying on the electroacoustic ... see more

Piranti-piranti elektronik maupun optoelektronik yang efisien dan responsif saat ini tengah masif dikembangkan dalam beragam bentuk dan jenis. Meta-material merupakan rancangan optoelektronik yang unik dengan sifat elektromagnetik yang tidak ditemukan sec... see more


An design method of electromagnetic metamaterial based on Lie symmetry transformation is proposed, which is applied to the regulation of electromagnetic wave / light. Firstly, the electromagnetic control model based on metamaterials is introduced, and the... see more
