• Terahertz
• Metasurface
• Location-dependent

Location-dependent metasurface with specific structure in terahertz (THz) range is designed and demonstrated, whose unit cell consists of coupled resonators, respectively, on the front and back sides of the polyimide substrate. Two transmission dips in the transmission spectrum are excited by electromagnetic interaction between the front and back resonators. Changeable width of the transmission window can be observed while shifting the front resonator away from its original place. Besides, horizontal and vertical change rule of the structure are all present in this paper. This location-dependent design of metasurface shows potential application on terahertz modulator, filter and sensor.
