A metal-wire/quantum-dot composite metamaterial with negative ε and compensated optical loss

A metal-wire/quantum-dot composite metamaterial with negative ε and compensated optical loss

Numerical simulations of a binary mixture of quantum dots exhibiting gain with silver nanorods are performed, showing the feasibility of lossless negative ε operation for realistic material structures and parameters.
