Abstract
We experimentally studied the tunable effects of connective dendritic left-handed metamaterials based on electrorheological fluids. Three influencing factors-the distance of electrodes, the permittivity of embedding media, and the intensity of applied electric fields-are discussed respectively. The experimental results show that the distance of electrodes exhibits an important effect on the transmission peak of the samples. The left-handed transmission peak shifts to lower frequency when the electrorheological fluids infiltrate. Moreover, by changing the intensity of electric field, the left-handed transmission peak can be modulated actively, and the maximum shift is up to 140 MHz.
