Abstract :
Three high-sensitivity metamaterial Terahertz DNA sensors based on resonance are proposed to distinguish DNA molecule with different refractive indices. Both numerical electromagnetic method and physical circuit model interpretation are employed to analyze proposed sensor structures. Design guideline based on intuitive physical circuit model is provided and verified through full-wave simulation.
