Implementing negative group delay by using SSPP units with equivalent single negative permeability

Classic circuits for spoof surface plasmon polaritons (SSPPs) usually introduce positive group delay, which leads to problems such as broadening of the pulse signal. In this regard, the SSPP structure with negative group delay (NGD) can be constructed to compensate the delay. However, there is a lac...
