Metasurface Magnetless Specular Isolator
Guillaume Lavigne, Toshiro Kodera, Christophe Caloz
We present a (nongyrotropic) metasurface magnetless specular isolator. This device reflects as a mirror a wave incident under a specified angle in one direction and absorbs it in t…
Unidirectional Loop Metamaterials (ULM) as Magnetless Artificial Ferrimagnetic Materials: Principles and Applications
Toshiro Kodera, Christophe Caloz
This paper presents an overview of Unidirectional Loop Metamaterial (ULM) structures and applications. Mimicking electron spin precession in ferrites using loops with unidirectiona…
Adaptive antenna system by ESP32-PICO-D4 and its application to web radio system
Toshiro Kodera
Adaptive antenna technique has an important role in the IoT environment in order to establish reliable and stable wireless communication in high congestion situation. Even if knowi…
Coupling Matrix Synthesis of Nonreciprocal Lossless Two-Port Networks using Gyrators and Inverters
Qingfeng Zhang, Toshiro Kodera, Shuai Ding +1
A coupling matrix technique is presented for the synthesis of nonreciprocal lossless two-port networks. This technique introduces complex inverters to build the nonreciprocal trans…
