Resonance Engineering via Harnessing Anti-Parallel Dipole Image Coupling
Dip Sarker, Abdoulaye Ndao
Precise control of plasmonic resonances across a broad spectral range is central to the development of tunable optical devices. Yet, achieving both redshifts and blueshifts within…

The Study of Optical Properties for Ordered and Disordered Silicon Nanowire Structures
Ohidul Islam, Dip Sarker, K. B. M. Sharif Mahmood +1
We designed ordered and disordered silicon (Si) nanowire structures and analyzed their optical performance using the finite-difference time-domain (FDTD) technique. We studied the…

Graphene Metamaterials Based Plasmon-Induced Terahertz Modulator for High-Performance Multiband Filtering and Slow Light Applications
Dip Sarker, Partha Pratim Nakti, Ahmed Zubair
We proposed multilayered graphene (Gr)-based surface plasmon resonance-induced high-performance terahertz (THz) modulators with tunable resonance frequencies. Several THz plasmonic…
