This volume introduces a new method for improving chip performance by harnessing the power of information transfer among chips at terahertz frequency. This revolutionary new electromagnetic wave engineering, called a spoof surface plasmon polariton, adapts the principles of VLSI and terahertz interconnect technology along with the artificial plasmonics to transfer huge quantities of data at vastly improved speeds. It constitutes a potentially decisive contribution to the pursuit of faster and more capacious VLSI chips.
