Spoof surface plasmon polaritons (SSPP) is a hybrid surface electromagnetic (EM) mode. When electromagnetic (EM) waves impinge on an EM media, free electros on the media surface will respond collectively by oscillating in resonance with the incident EM waves. The resonance interaction between the electrons and EM waves contributes to the SSPP and gives it’s a dual nature of wave and particle. On the side of the air, the SSPP propagates along the air-media interface, and the field perpendicular to the interface decays exponentially, behaving the wave nature. On the side of the media, the SSPP behaves the nature of electrons oscillation collectively. Field perpendicular to the interface still decays exponentially. However, amplitude of the oscillating electrons is smaller than that of the EM waves. Therefore, the SSPP has unique properties, such as field enhancement, sub-wavelength, non-linear frequency-dependent dispersion, and so on, promising great values in integrated circuits, antennas design, stealth materials or structures, electronic countermeasure applications, etc. In this paper, the recent progress of SSPP-based miniaturized microwave devices is reviewed, including microwave integrated circuits, filters, circulators, sensors, antennas, and orbital angular momentum (OAM) generators and so on. It provids reference to for the design and application of miniaturized microwave devices.
