论文摘要
提出了一种准确而快速的方法，用于从一系列时间调制石墨烯丝带中散射电磁波。我们在亚波长度近似下得出了诱导表面电流的时间域积分方程。使用谐波平衡方法，该方程用于正弦调制。然后，使用积分方程的解来获得时间调节的石墨烯色带阵列的传输和反射系数。通过与全波模拟的结果进行比较，验证了该方法的准确性。与先前报道的分析技术相反，我们的方法非常快，可以分析具有更高调制频率的结构。所提出的方法还提供了有趣的物理见解，可用于设计新型应用程序，并在基于时间调制石墨烯的设备的快速设计中打开新的远景。
An accurate and fast method is presented for scattering of electromagnetic waves from an array of time-modulated graphene ribbons. We derive a time-domain integral equation for induced surface currents under subwavelength approximation. Using the method of harmonic balance, this equation is solved for a sinusoidal modulation. The solution of the integral equation is then used to obtain the transmission and reflection coefficients of time-modulated graphene ribbon array. The accuracy of the method was verified through comparison with results of full-wave simulations. In contrast with previously reported analysis techniques, our method is extremely fast and can analyze structures with a much higher modulation frequency. The proposed method also provides interesting physical insights useful for designing novel applications and opens up new vistas in the fast design of time-modulated graphene-based devices.
