Abstract
Tuning devices and methods are disclosed. One of the devices comprises a metal structure connected with artificial dielectric elements, and variable capacitance devices. Each variable capacitance device is connected with a respective artificial dielectric element and with a control signal. Control of the variation of the capacitance allows the desired tuning. Another device comprises metallic structures connected with artificial dielectric elements and switches connected between the artificial dielectric elements. Turning ON and OFF the switches allows the capacitance between artificial dielectric elements to be varied and a signal guided by the metallic structures to be tuned.
