Abstract

This thesis studies one-dimensional structures based on a volume bounded by two metasurfaces. The main objective is to determine the properties of the metasurfaces such that under illumination by a normally incident plane wave the whole structure does not scatter; while the electromagnetic fields inside the bounded volume are not zero and can be tailored. Such invisible resonators are analysed from different perspectives: standing wave ratio, convergence, bandwidth, impact of dissipation losses, reciprocity, and effect of different objects inside the resonator. This thesis also introduces some concepts related to volumes bounded by multiple metasurfaces and some examples. Some applications for these resonators include cloaking and enhancing of low-power sensors.
