Fundamental research on the relationship between metamaterials and the structure in which the band gap occurs.

Abstract

In this paper, the relationship between the structure that serves as metamaterial and the structure in which the band gap occurs is investigated. The results can be summarised as follows: 1)When structure is added to the main system, the conditions for metamaterialisation are part of the conditions for band gap generation. 2)The band gaps that occur when the main system itself undergoes periodic changes cannot be described as metamaterials. 3)The application of the band gap generation mechanism showed the possibility of creating propagation structures that reduce vibrations in the desired frequency range by coupling systems that do not have natural frequencies in the desired frequency range with coupling elements until the required magnitude is reached.
