A note on power gain and directive gain
IEEE Antennas and Propagation Society Newsletter, 1978This comment refers to Dr. E. S. Gillespie's excellent article in,this issue and specifically to the terms power gain and directive gain. For some years a number of us have been concerned about the use of the above terms. The modifiers, "power" and "directive", were employed in the IRE Standards on Antennas-Methods of Testing, 1948 to eliminate the ...

Directive gain of corner antenna arrays
2004 14th International Crimean Conference "Microwave and Telecommunication Technology" (IEEE Cat. No.04EX843), 2004Questions of the directive gain calculation for radiating systems in terms of full and partial far-field patterns are considered in the paper pertaining to corner antenna arrays as an example.

Hybrid optical antenna with high directivity gain
SPIE Proceedings, 2013Coupling of a far-field optical mode to electronic states of a quantum absorber or emitter is a crucial process in many applications, including infrared sensors, single molecule spectroscopy, and quantum metrology. In particular, achieving high quantum efficiency for a system with a deep subwavelength quantum absorber/emitter has remained desirable. In

A Design Tool for Direct Solar Gain Evaluation
International Journal of Ambient Energy, 1991SYNOPSIS To design a passive building a careful assessment of the direct solar gain is required, so that the amount of solar energy collected by transparent surfaces can be determined. With this aim a computer package has been developed by means of which an hourly computation of the solar beam radiation coming into the building through oriented windows

Gain-scheduled direct eigenspace assignment control
1999 European Control Conference (ECC), 1999An adaptive control methodology, merging two known approaches to flight control problem, gain-scheduling and direct eigenspace assignment (DEA), is developed. A gain-scheduled inner (stability) loop structure is shown to minimize the variance of the outer (guidance) loop gains and increase the robustness of the system.

Characterization of gain and directivity of exponential horn receivers
The Journal of the Acoustical Society of America, 2017It is difficult and expensive to match the sensitivity of the most sensitive vertebrate ears with off-the-shelf microphones due to the self-noise of the sensor. The extremely small apertures of microelectromechanical microphones create options to use horn waveguides to amplify sound prior to transduction without resulting in an unacceptably narrow ...

RF gain control in direct conversion receivers
2002 IEEE International Symposium on Circuits and Systems. Proceedings (Cat. No.02CH37353), 2003This paper presents a study of LO self-mixing and RF gain control issues in direct conversion receivers. In cellular systems, that use continuous time frequency duplexing, these can constitute serious problems. The presented topic is of special importance when digitally programmable gain is implemented at the RF frequencies before the downconversion ...

High Raman gain directions in diamond
14th Pacific Rim Conference on Lasers and Electro-Optics (CLEO PR 2020), 2020We show how pump and Stokes beams propagating within a {111} plane in diamond can always have polarization parallel to the highest gain direction. We propose amplifier and monolithic laser geometries benefiting from such designs.
