Storage and release of electromagnetic waves using a Fabry-Perot resonator that includes an optically tunable metamirror
Yasuhiro Tamayama, Kengo Kanari
We evaluate the transient response of an optically tunable meta-atom composed of an electric inductor-capacitor resonator that is loaded with a piece of high-resistivity silicon an…
Tunable group delay in a doubly resonant metasurface composed of two dissimilar split-ring resonators
Yasuhiro Tamayama, Yutaro Kida
We develop a method to control the group delay of electromagnetic waves continuously using a doubly resonant metasurface. The method is based on the dependences of i) the group vel…
Frequency mixing at an electromagnetically induced transparency like metasurface loaded with gas as a nonlinear element
Yasuhiro Tamayama, Takuya Yoshimura
Local electromagnetic field enhancement in resonant metamaterials is useful for efficient generation of nonlinear phenomena; however, the field enhancement is suppressed by losses…
Design and analysis of frequency-independent reflectionless single-layer metafilms
Yasuhiro Tamayama
We develop a theory for realizing frequency-independent, reflectionless, single-layer metafilms based on the Brewster effect. A metafilm designed based on the theory is numerically…
Suppression of narrow-band transparency in a metasurface induced by a strongly enhanced electric field
Yasuhiro Tamayama, Keisuke Hamada, Kanji Yasui
We realize a suppression of an electromagnetically induced transparency (EIT) like transmission in a metasurface induced by a local electric field that is strongly enhanced based o…
Brewster effect in metafilms composed of bi-anisotropic split-ring resonators
Yasuhiro Tamayama
The Brewster effect is extended to single-layer metafilms. In contrast to bulk media, the Brewster effect in metafilms can be realized by tailoring the radiation pattern of a distr…
