The Frequency Selectivity of Double H-shaped Metallic Structures

摘要：

　　This paper presents the design and numerical simulation of the double H-shaped metallic periodic structure based on finite difference time domain(FDTD)method in terahertz frequency range.The double H-shaped structure unit cell consists of two H structures overlapped in the same plane.Numerical simulation results show that the double H-shaped structure results in a distinct and strong transmission trap in 0.2~3.0THz range.The position and the full wave at half maximum(FWHM)of transmission trap are changed with different structure size.The surface current distribution of structure is numerical simulated,which clarifies the frequency selection mechanism of the transmission spectra.
