Abstract: Various embodiments of the present invention are directed to global interconnects that employ metamaterial-based waveguides to distribute clock signals to IC internal components. In one embodiment of the present invention, a global interconnect includes an electromagnetic radiation source that radiates electromagnetic waves. The global interconnect also includes a metamaterial-based waveguide that directs a transverse magnetic field mode of the electromagnetic wave to antennae of the internal components in order to induce an oscillating current within the internal components that serves as the clock signal.
