“…The results affirm Fano resonance as a good candidate for achieving highly sensitive refractive index sensing capabilities, even at other regimes of the electromagnetic spectrum . It was further reported that a thinner substrate promotes a greater sensitivity when using such high‐ Q resonances as it allows for stronger interaction between the intense field and the analyte . With another two split gaps imposed onto the adjacent arms of the already asymmetric SRRs, Fano resonance and quadrupole resonance can be excited simultaneously, which could be utilized for thickness sensing and also to serve as a double referencing for increasing the accuracy of the sensing results .…”

Advances in plasmonic metamaterials have been rapidly evolving with innovations aimed at developing metadevices for real-world applications. In reality, energy losses in plasmonic systems are prevalent and it is of paramount importance to come up with solutions that could overcome the limitations that impede further advancements toward the miniaturization of optoelectronic metadevices. High-Q Fano resonance as a scattering phenomenon can be easily triggered by introducing asymmetry into plasmonic systems, and thus it offers a simple approach for reducing radiative losses through lineshape engineering. High-Q Fano resonance possesses narrow linewidth and intensely confined electromagnetic fields, which makes it viable for widespread applications. The purpose of this review is to consolidate the current advances and contributions that high-Q Fano resonance has made in the metamaterial community. Two general modes of energy loss including radiative and nonradiative losses are introduced and possible ways to overcome these challenges are examined. Furthermore, applications based on high-Q Fano resonance including sensors, lasing spasers, and optical switches are discussed, embracing the future of Fano resonance based high performance photonic technologies.

The purpose of this chapter is to convey a message that the variety of applications of the classical (and the novel ones, such as Mie resonance based) metamaterials are going far beyond the originally proposed applications such as geometrical optics and antennas. In addition, it is important to mention that most of these applications are just an idea or a first proof of principle. Hence, an additional message of this chapter is that a lot of further research is required to implement these scientifically sound ideas. It is also a hope that this chapter will trigger the reader's curiosity and interest to pursue this exciting field, which will yield additional applications that have never been imagined.
