“…Modulation technology is the basis of modern communication systems, including plasmonic ones (Xiao et al, 2015;Zhang, Sun et al, 2016). A 70 GHz plasmonic Mach-Zehnder modulator was reported with a dramatic reduction of size, low energy consumption, and ultrahigh speed (Haffner et al, 2015).…”

In undergraduate courses on classical electromagnetism, it is taught that a perfect conductor expels the electromagnetic (EM) field, and hence its surface is not able to support the propagation of bound EM waves. However, when the surface of a perfect conductor is structured at a length scale much smaller than the operating wavelength, geometrically induced surface EM modes can be supported. Owing to their similarities with the surface plasmon polaritons (SPPs) in the optical regime, these surface EM modes were named spoof surface plasmons. The concept of spoof surface plasmons has opened up a new line of research within plasmonics with the aim of transferring all the potentialities of SPPs in the optical regime to lower frequencies (microwave, terahertz, and midinfrared regimes) in which a metal behaves as a quasiperfect conductor. In recent years, several research groups have extended this concept from planar surfaces to waveguides, and eventually to resonators, covering the entire range of structures studied in standard plasmonics. This review provides a detailed perspective on the recent developments in spoof surface plasmon photonics from both the fundamental and applied sides.

“…The conversion structures of microstrip line and coplanar waveguide (CPW) to SSPPs transmission are proposed, making it possible to investigate its transmission performance and integrate with classical transmission lines [14,15,16]. The SSPPs structures with underlayer ground is also a convenient way to integrate with microstrip lines [17,18]. The conversion efficiency between microstrip line and SSPPs structures with underlayer ground is higher than [15,16].…”

In this letter, odd-mode and even-mode spoof surface plasmon polaritons (SSPPs) supported by complementary plasmonic metamaterial with underlayer ground are investigated. The dispersion characteristics and electric field distributions of the odd-mode and even-mode SSPPs are studied. Different high-efficiency conversion structures are proposed to realize the excitation of odd-mode and even-mode SSPPs transmissions. The odd-mode and even-mode SSPPs transmission lines are simulated and measured. The measured insertion losses of odd-mode transmission line are within 2.58 ² 1.23 dB from 3.0 to 10.0 GHz. The measured insertion losses of even-mode transmission line are within 1.66 ² 1.18 dB from 2.0 to 12.0 GHz. The simulation and measurement results validate the highefficiency excitation and excellent propagation performance of odd-mode and even-mode SSPPs on the complementary plasmonic metamaterial with underlayer ground in the microwave frequencies.

A tunable spoof surface plasmon transmission line (SSP‐TL) is proposed and investigated, which is periodically loaded with varactors and short‐circuit stubs. Compared with the common SSP‐TL with open‐circuit stubs, the proposed SSP‐TL exhibits better compactness and higher tunability. The dispersion and impedance features are analyzed using the T‐matrix method. The proposed SSP‐TL can also be biased in a conventional microstrip bias circuit, and seamlessly integrated into microstrip circuits. As applications, a frequency‐reconfigurable and compact Wilkinson power divider is designed and fabricated using the proposed SSP‐TL as the λ/4 impedance transformer around 1 GHz, which is validated by both numerical and experimental results. It is shown that 35% (or 20%) frequency tunability is achieved in simulated (or measured) results, reducing the footprint to 46% of the conventional microstrip one.
