Effect of Unit Cell Shape on Switchable Infrared Metamaterial VO2 Absorbers/Emitters

Figure 3

(a) The inductor-capacitor (LC) circuit consists of capacitors and inductors, which will resonate at MP frequency. The imaginary part of impedance at the resonant frequency needs to become zero if the condition of perfect absorption is achieved. (b) The magnetic field distribution when VO2 is in insulating state at - views crosses the center VO2 of triangle, square, hexagon, and circle cell at resonant wavelengths.
