Abstract

In this paper, graphene based tunable bandpass and bandstop filters are designed in terahertz frequency regime using a triangular microstrip patch resonator. Initially, a bandpass filter is designed at an operating frequency of 1.65 THz with a bandwidth of 65 GHz. Further a dual-band bandstop filter is designed with resonance frequencies of 1.25 THz and 2.14 THz. In both designs, the triangular patch is coupled to the transmission line to achieve bandpass and bandstop characteristics. A graphene layer is deposited between the dielectric and the conductor layer to enhance the propagation of plasmonic waves. The simulation results reveal that the designed filters are capable of achieving the desired frequency response. By varying the graphene’s chemical potential, a shift in the transmission response’s resonance frequency is observed. The proposed filters have the potential to be used as key components for future terahertz band communications systems.

用于太赫兹应用的基于石墨烯的三角形贴片谐振器滤波器设计

本文利用三角形微带贴片谐振器，在太赫兹频率范围内设计了基于石墨烯的可调谐带通和带阻滤波器。最初，带通滤波器设计在1.65 THz的工作频率下，带宽为65GHz。此外，设计了具有1.25THz和2.14THz的谐振频率的双频带阻滤波器。在这两种设计中，三角形贴片都耦合到传输线，以实现带通和带阻特性。石墨烯层沉积在电介质和导体层之间，以增强等离子体波的传播。仿真结果表明，所设计的滤波器能够达到期望的频率响应。通过改变石墨烯的化学势，可以观察到传输响应共振频率的变化。所提出的滤波器有可能被用作未来太赫兹波段通信系统的关键部件。
