Abstract :
Here we present a novel qausi-static dynamic RLC model for terahertz perfect absorbers. The model fits perfectly to both simulation and measurement data for our designed absorber. By using this model we analyze our simulated and fabricated perfect absorber to figure out operational mechanism behind these kinds of absorbers. The model can explain well the physical principle behind these kinds of absorbers based on interference theory of reflected waves.
