Adaptive impedance matching in microwave and terahertz metamaterial absorbers using PIN diodes and GaN HEMTs
Metamaterial absorbers allow electromagnetic waves to be converted into heat energy based on impedance matching. However, passive metamaterial absorbers exhibit fixed absorption characteristics, limiting their flexibility. This work demonstrates tunable microwave and terahertz absorbers by integrati...
