THz absorber for breast cancer early detection based on graphene as multi-layer structure

Today, the cost of treating cancer is very high at medical center. So, early detection essential, and one possible ways to diagnose in stages use sensors that are made terahertz area. The proposed absorber a multilayer structure which graphene used upper middle layer has ribbon form. A disk form element for layer. Finally, ring added structure. In final absorber, actually encompasses field, this will increase Q-factor 6.7 THz. interaction layers on each other their effect reflection studied modify by variation chemical potential range 0.2 0.6 eV. discriminate healthy breast tissue. thickness distance tissue from examined realize material sensitivity figure merit (FOM) as two main factors detecting
