Ferroelectric materials and metamaterials for a new approach to ITER-ICRH loads

摘要

This paper presents a new approach for ICRH loads used in laboratory testing. Classical "water" loads are convenient but strongly limited in terms of performances. Development of high permittivity loads is under investigation to improve ICRF antenna laboratory testing. Ferroelectric BaTiO_3 ceramic materials along with metamaterials are shown to be promising candidates.
