| Research Abstract |
This study investigates composite right- and left-handed (CRLH) transmission lines periodically loaded with Schottky varactors to examine the fundamental properties and potential applications of nonlinear metamaterials. The analytical properties of nonlinear pulses in the line were first obtained by the reductive perturbation method, which were confirmed by several experimental measurements. In one dimension, we succeeded in the observation of solitary waves and their resonant interactions, while the self-focused pulse was clearly observed in two dimensions. A method of the wave amplification using traveling-wave field-effect transistors were newly devised to widen the future fields of applications.
