Highly compact tunable hourglass-shaped graphene band-stop filter at terahertz frequencies
Results in Optics, 2023 In this research paper, we introduce a band-stop filter based on an hourglass-shaped graphene nanoribbon topology. Employing the three-dimensional finite difference time domain (3D-FDTD) method, we conduct comprehensive numerical simulations to ...
