Broadband control of group delay using the Brewster effect in metafilms
Yasuhiro Tamayama, Hiromu Yamamoto
We propose and verify a method for controlling the frequency dependence of the group delay of electromagnetic waves over a broad frequency range using the Brewster effect in single…
Low-power threshold gas discharge by enhanced local electric field in electromagnetically-induced-transparencylike metamolecules
Yasuhiro Tamayama, Ryosuke Yamada
To realize efficient nonlinear metamaterials, we investigate a method for enhancing the local electric field in a metamolecule composed of two radiatively coupled cut-wire resonato…
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…
Microplasma generation by slow microwave in an electromagnetically induced transparency-like metasurface
Yasuhiro Tamayama, Osamu Sakai
Microplasma generation using microwaves in an electromagnetically induced transparency (EIT)-like metasurface composed of two types of radiatively coupled cut-wire resonators with…
