Propagation of hybrid transverse magnetic-transverse electric plasmons on magnetically biased graphene sheets

摘要: The propagation of plasmons on magnetically biased graphene sheets is addressed. analysis based the transverse resonance method extended to handle conductivity tensor and allows easily accounting for substrate effects. A transcendental equation obtained constant resulting hybrid magnetic-transverse electric mode. closed-form approximate expression a layer sandwitched between two different media also provided. Application shows that presence magnetic field leads extreme localization, namely, very small guided wavelength, as compared with usual in or noble metals. extent localization its frequency can be dynamically controlled by modifying applied magnetostatic electrostatic bias field, respectively. These features could enable device miniaturization enhanced resolution sensing applications.
