In a magnetic field configuration of the Large Helical Device (LHD), when the extraordinary mode (X-mode) waves are obliquely injected from a bottom antenna, it can directly access the upper hybrid resonance (UHR) layer from the high field side and excite electron Bernstein waves (EBWs) without the need for any additional reflecting mirror antenna. A localized power absorption is observed in the low field side of the electron cyclotron resonance (ECR) layer. This result suggests electron
