N2 - We introduce and experimentally demonstrate a class of fully programmable digitally controlled metamaterials. An elastic waveguide is connected to synthetic impedance circuits as active elements to enable simultaneous control over the center frequency, attenuation, and bandwidth of resonant band gaps. The experimental results demonstrate digital tuning over a wide frequency range that spans several modes of the waveguide. This platform opens avenues to achieving precise control over effective metamaterial properties and their possible space-time modulation, paving the way for digitally controlled programmable wave devices.
