Reaction-Diffusion Driven Patterns in Immiscible Alloy Thin Films
Vivek C. Peddiraju, Shourya Dutta-Gupta, Subhradeep Chatterjee
Controlling the microstructure of thin films is of critical importance for various applications. We demonstrate a methodology for tuning the local microstructure through film-subst…
Substrate interaction mediated control of phase separation in FIB milled Ag-Cu thin films
Vivek C. Peddiraju, Pravallika Bandaru, Shourya Dutta-Gupta +1
Nanofabrication is an integral part of realization of advanced functional devices ranging from optical displays to memory devices. Focused ion beam (FIB) milling is one of the wide…
Electrical Tuning of Polarizaion-state Using Graphene-Integrated Metasurfaces
Nima Dabidian, Shourya Dutta-Gupta, Iskandar Kholmanov +2
Plasmonic metasurfaces have been employed for tuning and controlling light enabling various novel applications. Their appeal is enhanced with the incorporation of an active element…
Experimental Demonstration of Phase Modulation and Motion Sensing Using Graphene-Integrated Metasurfaces
Nima Dabidian, Shourya Dutta-Gupta, Iskandar Kholmanov +8
Plasmonic metasurfaces are able to modify the wavefront by altering the light intensity, phase and polarization state. Active plasmonic metasurfaces would allow dynamic modulation…
Coherent perfect absorption mediated anomalous reflection and refraction
Shourya Dutta-Gupta, Rahul Deshmukh, Achanta Venu Gopal +2
We demonstrate bending of light on the same side of the normal in a free standing corrugated metal film under bi-directional illumination. Coherent perfect absorption (CPA) is expl…
Controllable coherent perfect absorption in a composite film
Shourya Dutta-Gupta, Olivier J. F. Martin, S. Dutta Gupta +1
We exploit the versatility provided by metal--dielectric composites to demonstrate controllable coherent perfect absorption (CPA) in a slab of heterogeneous medium. The slab is ill…
