Abstract: A metamaterial for deflecting an electromagnetic wave is disclosed, which comprises a functional layer. The functional layer comprises a plurality of sheet layers parallel to each other, and each of the sheet layers comprises a sheet-like substrate and a plurality of man-made microstructures arranged in an array on the sheet-like substrate. The sheet-like substrate comprises a plurality of unit blocks, and each of the man-made microstructures and a corresponding one of the unit blocks occupied thereby form a unit cell. Refractive indices of the unit cells arranged in a first direction in each of the sheet layers decrease gradually. Each of the unit cells has an anisotropic electromagnetic parameter.

Abstract: The present disclosure provides a unipolar MIMO antenna, which consists of a plurality of unipolar RF antennae. Each of the unipolar RF antennae comprises a metal sheet and a feeder line. The metal sheet is enchased with a metal microstructure thereon, and the feeder line and the metal sheet are connected in a signal communicative manner. The unipolar MIMO antenna of the present disclosure breaks through the framework of the conventional antenna design and eliminates the complex design of the impedance matching network to ensure miniaturization of the antenna. Thereby, the antenna can be used in a wireless apparatus having a small size, a high transmission efficiency and a high isolation degree among antennae and can satisfy the requirement of a low power consumption in the design of modern communication systems. Additionally, the present disclosure further provides a bipolar MIMO antenna and a hybrid MIMO antenna.

Abstract: The present disclosure relates to an electromagnetically transparent metamaterial, which comprises a substrate and a plurality of man-made metal microstructures arranged periodically inside the substrate. When an electromagnetic wave propagates through the metamaterial, each of the man-made metal microstructures is equivalent to two identical two-dimensional (2D) circuits, which are placed respectively in a direction perpendicular to an incident direction of the electromagnetic wave and in a direction parallel to the incident direction of the electromagnetic wave, and each of which comprises an inductor branch and two identical capacitor branches that are symmetrically connected in parallel with the inductor branch. The 2D circuits are associated with a waveband of the electromagnetic wave so that both a dielectric constant and a magnetic permeability of the metamaterial are substantially 1 when the electromagnetic wave propagates through the metamaterial.
