Energy exchange between surface plasmon polaritons and CdSe/ZnS quantum dots
Kunal Tiwari, Suresh C Sharma, Hussein Akafzade +1
Evidence is presented for energy exchange between surface plasmon polaritons (SPPs) excited in waveguide-coupled Ag/Si3N4/Au structures and CdSe/ZnS quantum dot (QD) emitters. The…
Application of single metal Au and Ag/Si3N4/Au plasmonic sensors for glucose refractive index measurements
Hussein Akafzade, Nader Hozhabri, Suresh C Sharma
We have employed single gold layer metal and multilayer Ag/Si3N4/Au plasmonic sensors to monitor changes in the refraction index of glucose/water solutions. Our results show that t…
Controlling electrical conduction through noble metal thin films by surface plasmon resonance
Suresh C Sharma, Vivek Khichar, Hussein Akafzade +1
The collective oscillations of surface charges (surface plasmons) induced by light-matter interactions were predicted in the 1950s to influence electrical conduction in 2D noble me…
Inhomogeneous Energy - Density Driven Instability in Presence of a Transverse DC Electric Fields in a Magnetized Plasma Cylinder
Suresh C. Sharma, Satoshi Hamaguchi
Temporal evolution of the inhomogeneous energy density driven instability (IEDDI) is examined in presence of a nonuniform transverse dc electric field in collisional magnetized pla…
Current-Driven Dust Ion-Cyclotron Waves in Presence of a Transverse DC Electric Fields in Magnetized Plasma with Charge Fluctuations
Suresh C. Sharma, Satoshi Hamaguchi
The current-driven electrostatic ion-cyclotron (EIC) instability is studied in presence of a transverse dc electric fields in a collisional magnetized dusty plasma. We derive the a…
Gain and Efficiency Enhancement in Free Electron Laser by Means of Modulated Electron Beam
Vivek Beniwal, Suresh C. Sharma, Satoshi Hamaguchi
Beam premodulation on free electron laser (FEL) offers considerable enhancement in gain and efficiency when the phase of the premodulated beam is -pi/2 and the beam is highly modul…
