Tunable Terahertz Absorption with Optical Tamm State in the Graphene-Bragg Reflector Configuration

<div>Reflectance of the graphene-DBR structure as a function of the dielectric constant and thickness. (a) Absorption rate varies with different top layer different dielectric constants, where the dielectric constant ranges from 1.7 to 2.3. (b) Absorption rate varies with different top layer different thicknesses, where the thickness ranges from 30 <i>μ</i>m to 36 <i>μ</i>m.</div>
