In the past decade, metamaterials have attracted a lot of attention because of their abilities to exhibit unusual electromagnetic properties. These properties are exploited in designing functional components and devices for many potential applications. In this chapter, we review the theory and design of metamaterial structures for microwave near‐field imaging/microscopy. The chapter highlights metamaterial microwave components to obtain super‐resolution and manipulating subwavelength images. Moreover, a review on surface plasmons manipulation at microwave frequencies is presented as a technique to enhance the transmission for near‐field microscopy. The chapter presents as well a survey on the near‐field imaging instrumentation and its advances mainly for microwave and THz regimes.
