Detecting stimulated-Raman responses of few molecules using Optical Forces
Venkata Ananth Tamma, Lindsey M. Beecher, Jennifer S. Shumaker-Parry +1
We demonstrate the stimulated Raman near-field microscopy of few molecules, measured only using near-field optical forces thereby eliminating the need for far-field optical detecti…
Measurement of Laterally Induced Optical Forces at the Nanoscale
Fei Huang, Venkata Ananth Tamma, Hemanta Kumar Wickramasinghe
We demonstrate the measurement of laterally induced optical forces using an Atomic Force Microscope (AFM). The lateral electric field distribution between a gold coated AFM probe a…
Theory and New Amplification Regime in Periodic Multi Modal Slow Wave Structures with Degeneracy Interacting with an Electron Beam
Mohamed Othman, Venkata Ananth Tamma, Filippo Capolino
We present the theory of a new amplification regime in Travelling Wave Tubes (TWTs) composed of a slow-wave periodic structure that supports multiple electromagnetic modes that can…
Photo-induced Magnetic Force Between Nanostructures
Caner Guclu, Venkata Ananth Tamma, Hemantha Kumar Wickramasinghe +1
Photo-induced magnetic force between nanostructures, at optical frequencies, is investigated theoretically. Till now optical magnetic effects are not used in scanning probe microsc…
Novel concept for pulse compression via structured spatial energy distribution
Venkata Ananth Tamma, Alexander Figotin, Filippo Capolino
We present a novel concept for pulse compression scheme applicable at RF, microwave and possibly to optical frequencies based on structured energy distribution in cavities supporti…
Extension of Pierce model to multiple transmission lines interacting with an electron beam
Venkata Ananth Tamma, Filippo Capolino
A possible route towards achieving high power microwave (HPM) devices is through the use of novel slow-wave structures, represented by multiple coupled transmission lines (MTLs), a…
