Special Issue Information

Dear Colleagues,

In recent years, the development of plasmonics and metamaterials has gained significant attention from scientists and technologists. Based on their extraordinary light manipulation ability, diversified optical functions have been realized, including beam steering and beam shaping, while the working waveband covers from ultraviolet to microwave. In addition to optics, the applications of metamaterials are being extended to acoustics, thermotics, and many other subjects. Thereby, the development of plasmonics and metamaterials promotes the development of many scientific areas such as information technology, nanophotonics, and biosensing. Potentially, with the improvement of computing power and nanofabrication technology, diversified plasmonic and metamaterial structures with different shapes, materials, and arrangements can be designed and fabricated at lower cost, inspiring novel applications and entering our daily lives.

In this Special Issue, the latest progress of plasmonics and metamaterials is highlighted and discussed, including but not limited to theory research, material or structure innovation, fabrication method development, and application expansion.

It is my pleasure to invite you to submit a manuscript for this Special Issue. Articles, letters, and reviews are all welcome.

In this paper, the design of a double-band terahertz metamaterial filter with broadband characteristics using a single conducting layer is presented. The design uses a structured top metallic layer over a polyimide material. The proposed design has achieved broadband band-pass transmission characteristics at the resonances of 0.5 THz and 1.65 THz, respectively. The 3-dB bandwidths for these two resonances are 350 GHz and 700 GHz, respectively, which indicates that dual-band resonance with broadband transmission characteristics was obtained. The design has achieved the same transmission characteristics for two different orthogonal polarizations, which was confirmed using numerical simulation. The design was tested for a different angle of incidences and it was observed that this results in angle-independent transmission behavior. In addition, for obtaining tunable resonant behavior, the top conductor layer was replaced by graphene material and a silicon substrate was added below the polymer layer. By varying the Fermi level of graphene, modulation in amplitude and phase was observed in numerical simulation. The physical mechanism of double-band behavior was further confirmed by surface current distribution. The proposed design is simple to fabricate, compact, i.e., the size is λ0/8, and obtained dual-band/broadband operation. Full article
