Understanding the chemical composition and morphology of interfaces plays a vital role in the development of sensors, drug delivery systems, coatings for biomedical implants, and so forth. In many ...

This article presents a method for metal defect detection by using the surface plasmon polaritons (SPP). This is a type of transverse magnetic (TM) electromagnetic wave which can only exist on a metal ...

A new silicon germanium (SiGe)-based D-band lowpass filter (LPF) is proposed utilizing on-chip spoof surface plasmon polaritons (SSPPs). By analyzing the unique dispersion characteristics, the cutoff ...
