Waveguide characteristics of adjustable magnetorheological mechanical topological insulator

A structure of tunable magnetorheological mechanical topological insulator that uses magnetorheological elastomers as matrix and pure iron as scatterer is designed. By changing the external magnetic field, the elastic modulus of the matrix is affected, and the size and width of the bandgap are adjus...
