The investigation of arm width in terahertz cross metal structures

In this paper, the effects of the arm length and the width of cross-dipole and Jerusalem cross on resonance characteristics are investigated. By adjusting the geometry parameters of the two kinds of cross structures, the influence of arm length and width on the equivalent inductance and equivalent capacitance is analyzed by the simulations. The comparative analysis demonstrates that the width of cross-dipole has more influence on the equivalent inductance than equivalent capacitance. The conclusions in this paper would useful in the calculation of the equivalent inductance and capacitance in the LC resonance.
