Adaptive beam-size control scheme for ground-to-satellite optical communications
(Society of Photo-Optical Instrumentation Engineers, Bellingham, WA, United States, 1999)Atmospheric turbulence severely degrades the performance of ground-to-satellite optical links. Employment of adaptive optics to enhance ground-to-space optical communication systems has recently been considered and possible ... -
Optimum beam size for laser beam propagating through atmospheric turbulence
(1999)A previous study concluded that the optimum beam diameter for a laser beam propagating through atmospheric turbulence is of the order of the coherence scale. It is shown that the optimum size is critically dependent on ... -
Analytic formulas for calculating the quasistatic parameters of a multilayer cylindrical coplanar strip line
(John Wiley and Sons Limited, 1999)Fast, simple, and accurate analytic expressions are derived for calculating the quasistatic TEM parameters of a multilayer cylindrical coplanar strip line (MC CPS). The effects of the dielectric materials on the quasi-TEM ... -

Reduced-size dual-mode slotted patch resonator for low-loss and narrowband bandpass filter applications
(2004)A compact, low-loss and narrowband dual-mode microstrip filter is proposed using degenerate modes of a microstrip patch resonator loaded with two narrow slots. The resonator structure is fed by inset lines connected directly ... -
Slow-wave CPW resonator with defected ground structure (DGS) for filter applications
(2006)Novel slow-wave CPW resonators with defected ground structures (DGSs) in a rectangularly spaced and open-loop shapes are investigated. These structures have an extremely compact size. The simulations and experimental results ... -
Higher order annular Gaussian laser beam propagation in free space
(2006)Propagation of higher order annular Gaussian (HOAG) laser beams in free space is examined. HOAG beams are defined as the difference of two Hermite-Gaussian (HG) beams; thus, they can be produced by subtracting a smaller ... -
Bandstop Filter Using Slow-wave CPW Resonator with Defected Ground Structure
(The Electromagnetics Academy, 2009)A novel slow-wave CPW resonator with defected ground structures (DGSs) in rectangular spacing-like shapes is investigated. This structure has an extremely compact size. Simulations and experimental results have verified ... -
Fine Tuning the Advanced Encryption Standard (AES)
(Association for Computing Machinery, 2012)The Advanced Encryption Standard has been playing a prominent role in embedded systems security for a decade after being announced by the National Institute of Standards and Technology (NIST). However, vulnerabilities have ... -
A broker-based semantic agent for discovering Semantic Web services through process similarity matching and equivalence considering quality of service
(SCIENCE PRESS, 2013)The lack of semantic descriptions for "web service properties" makes it difficult to find suitable web services. Current solutions are mostly based on broker/mediator agent systems. However, these techniques are syntactical, ... -
