A novel optically transparent, flexible, and mechanically reconfigurable zeroth-order resonant (ZOR) antenna using stretchable micromesh structure is presented in this paper. The size reduction of the antenna is achieved by using the ZOR property, and the uniform metallic patches of the antenna are replaced with the tortuous micromesh. The tortuous micromesh structures provide a high degree of freedom...
Hyperbolic meta-materials based on ultrathin metal-dielectric multilayers have been studied by considering the nonlocal response of electrons in metal. We show that nonlocality will induce topological transitions of the iso-frequency surfaces and limit light-matter interactions.
We propose a method for deep-subwavelength patterns using antisymmetric surface plasmon mode in metal/dielectric multilayer metamaterials. Interference patterns with feature size of 22nm(∼λincident/20) and fabrication of the device are demonstrated.
Split ring resonators (SRRs) have been widely studied as fundamental elements of metamaterials showing magnetic response. In order to search for metamaterials with negative refractive index, we studied the electromagnetic properties of structures with modified SRRs. We proposed a structure composed of continuous SRRs showing both negative μ and negative ε. Experimental results are supported by numerical...
