Silver nanoparticles in nonlinear microscopy

D. J. Rativa; A. S. L. Gomes; S. Wachsmann-Hogiu; D. L. Farkas; R. E. de Araujo 2007 SBMO/IEEE MTT-S International Microwave and Optoelectronics Conference, 2007

Nanotechnology has led to the manufacture of nanometer-sized objects which can be explored in multiphoton microscopy. In particular, metal nanoparticles (NPs) do not generate the multiphoton signal by itself, but rather it can enhance the nonlinear (NL) emission of fluorochromes, owing to the influence of local field effects. Energy transfer process is also observed in systems consisting of metal nanoparticles ...

The operation of a crystalline silicon solar cell was studied by a methodology based on collection efficiency. The quantum efficiencies of the base, emitter, and depletion layers were determined separately using numerical solutions. The collection efficiency was then determined by the reciprocity theorem. It is shown that the model can provide useful new insight and can be used to extract ...


Evaluation of collision frequency in high-pressure glow discharges

T. George; L. Denes; L. Kline IEEE Journal of Quantum Electronics, 1977

We have used far infrared absorption techniques to measure the time resolved electron-neutral collision frequency in pulsed high-pressure glow discharges in nitrogen, helium, and CO2laser mixtures. The equilibrium collision frequency for a constant applied electric field has also been calculated as a function ofE/N, the electric field-to-gas density ratio. The measured and calculated collision frequencies are in good quantitative agreement. ...

  • About the Authors

    A lucid and up-to-date introduction to understanding electrical power utilities in an era of change Electric utilities worldwide are undergoing profound transformations: nationally owned systems are becoming privatized, privately owned systems that were previously regulated are becoming deregulated, and national systems are becoming international. Professionals in the power sector must now work in a new world in which an understanding of the principles of markets and how to evaluate investment projects under competition are essential. This text was written as a manual for the Russian Federal Energy Commission to train regional electricity rate regulators in the principles of economics and finance involved in regulating electricity markets and deregulating electricity generation. Requiring no familiarity with economics and using a minimum of mathematics, this book provides professionals in the power sector with the tools to face the new realities of electric utility operation. Designed both as a reference for practicing professionals and as a textbook for university and continuing education programs, Electricity Economics: Regulation and Deregulation discusses: The lessons learned from international experiences Competitive versus noncompetitive markets Cost and supply, profit, and economic efficiency The cost of capital, including net present value, discounting, and risk and return Wholesale power markets, generation expansion, and customer choice Specific international examples including the Californian, Norwegian, Spanish, and Argentine power sectors Plus numerous exercises to help clarify and support absorption of the concepts

  • Handset Antennas for Mobile Communications: Integration, Diversity, and Performance

    The evolution of mobile communications has increased the need for more-complex antennas on the mobile side than the standard whip antenna. The need arises from several aspects, one being the cautionary measure of limiting the absorption and absorption density in the user's head, the other being optimization of the communication quality, including ease of use. Although not used widely as yet, antenna diversity on the handset has the important possibility of improving the performance. Knowledge about the spatial distribution of energy around the user is necessary for the evaluation of mean effective gains and correlation coefficients for mobile antennas. This, together with numerical and experimental results for radiation patterns from various antennas, including the effect of the user, determines the end performance measures. Antennas discussed are patch, helical, and dipole antennas integrated within or outside the phone itself. The effect of different users on the performance is also of interest, since it turns out that the variability from person to person is quite large, and that the variations are reproducible. This means that testing antennas for this application is a complicated process.

  • Regulations Related to Antenna Engineers

    This chapter introduces various regulations which are related to antenna engineers. There are mainly three topics: (1) Specific Absorption Rate (SAR), which is about the radiation to the human head and body; (2) Hearing Aid Compatibility (HAC), which is about the electromagnetic compatibility with hearing aids; and (3) Electromagnetic Compatibility (EMC), which is about the electromagnetic compatibility with other devices.

  • New Generation of Vertical???Cavity Surface???Emitting Lasers for Optical Interconnects

    This chapter addresses requirements for vertical???cavity surface???emitting lasers (VCSELs), one of the major devices for data communication to meet the bandwidth demand. Single???mode (SM) operation makes it possible to overcome effects related to significant spectral dispersion of the multimode fiber (MMF) standardized for the 840???860nm wavelength range. The leaky VCSEL concept can allow SM operation without any adjustments in the oxide???confined VCSEL technology and does not require sacrificing the basic VCSEL parameters. The chapter investigates oxide???confined, leaky???design VCSELs and observes the characteristic leakage???effect???induced features in the vertical far???field pattern of the device. This observation confirms the validity of the leaky VCSEL concept, allows for better understanding of the device properties such as possible strain and heat gradients, oxide layer tapering, in???plane light scattering, and absorption. The chapter enables the engineering of advanced devices and photonic???integrated circuits with targeted design of oxide apertures or air gaps through quantitative evaluation of the leaky emission.
