Title:
META-MATERIAL DEVICE AND ANTENNA DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/044000
Kind Code:
A1
Abstract:
This meta-material device is provided with at least one unit resonator (1). The unit resonator (1) is provided with a resonance element (21), and a pair of reflection elements (22). The resonance element (21) has a strip shape having first and second end parts, has a path that does not include a parallel circuit section in which current flows simultaneously in reverse directions between the first and second end parts, and has substantially zero effective magnetic permeability. Each of the pair of reflection elements (22) is connected respectively to the first and second end parts of the resonance element, and the impedance when each reflection element (22) is viewed from the resonance element (21) becomes substantially zero. The unit resonator (1) operates as a zero-order resonator.
