Abstract

The invention provides an ultrathin flexible electric-heating tunable meta-material based on a three-dimensional Ohm structure and preparation of the same. The meta-material comprises a flexible parylene-C substrate and the three-dimensional Ohm structure, wherein the three-dimensional Ohm structure is composed of a lower parylene-C dielectric layer and an upper metal layer; and the three-dimensional Ohm structure is an Ohm ring or an Ohm circle. According to the invention, a dielectric medium and metal with different residual stresses and thermal expansion coefficients constitute the three-dimensional Ohm structure; and current or temperature control is used to control a relative rotation angle between the three-dimensional Ohm structure and the parylene-C substrate, so that continuous tuning is implemented to resonant frequency of electromagnetic responses. The meta-material provided by the invention has the advantages that structural design is novel; processing technologies are simple; a sacrificial layer is not needed; non-planar applications of the meta-material can be realized; and the continuous tuning can be implemented to the resonant frequency of the electromagnetic responses of the meta-material and incident electromagnetic waves.

Description

technical field [0001] The invention relates to a device of micro-nano processing technology, in particular to an ultra-thin flexible electrothermal tunable metamaterial based on a three-dimensional ohmic structure and its preparation. Background technique [0002] Metamaterials mainly refer to composite or non-periodic man-made structural unit arrangements that are manufactured through strict and complex artificial design and processing based on application requirements and human will, starting from atomic or molecular design. Miscellaneous materials. This kind of material can exhibit extraordinary physical properties that natural materials do not have, that is, negative refractive index, negative magnetic permeability, negative dielectric constant and other peculiar properties. The properties of metamaterials can be applied to the development of functional devices, such as surface plasmon photonic chips, filters, couplers, modulators and switches, super-diffraction-limite...
