Enhanced solar absorbance and infrared emittance in Co-doped BaTiO3

Modified Lossy epsilon-negative CuCr2Se4 toward single-phase metamaterials with double negative parameters via Zn doping

“…28 Veslago considered utilizing semiconductive spinels as potential candidates for single-phase metamaterials. However, the synthesis process was proven to be challenging, the particle size of the spinel has an important effect on the performance, 29 and ion doping will also cause lattice distortion, 30 which further affects the performance, and ultimately leads to failure. Hence, discovering a series of single-phase materials with random DNMs and broadening the double negative frequency range is of utmost importance.…”
