FPGA Implementation of Embedded Fuzzy Controllers for Robotic Applications
(Institute of Electrical and Electronics Engineers, 2007)
Fuzzy-logic-based inference techniques provide efficient solutions for control problems in classical and emerging applications. However, the lack of specific design tools and systematic approaches for hardware implementation ...

Analytical theory of wave propagation through stacked fishnet metamaterials
(Optical Society of America, 2009)
This work analyzes the electromagnetic wave propagation through periodically stacked fishnets from zero frequency to the first Wood's anomaly. It is shown that, apart from Fabry-Perot resonances, these structures support ...

Efficient realization of RTD-CMOS logic gates
(2011)
The incorporation of Resonant Tunnel Diodes (RTDs) into III/V transistor technologies has shown an improved circuit performance: higher circuit speed, reduced component count, and/or lowered power consumption. Currently, ...

Asymmetric clock driver for improved power and noise performances
(IEEE Computer Society, 2007)
One of the most important sources of switching noise and power consumption in large VLSI circuits is the clock generation and distribution tree. This paper analyzes how the use of an asymmetric clock can be an ...

Molecular dynamics simulations of homogeneous solids using multi-layered structures
(IOP Publishing Ltd., 2008-07)
The main goal of this work is to model a homogeneous computer material with well-defined mechanical properties. To carry out the model material, an internal structure arranged in layers with different atom sizes is implemented ...

Numerical implementation of the mixed potential integral equation for planar structures with ferrite layers arbitrarily magnetized
(Wiley-Blackwell, 2006)
This work presents a new implementation of the mixed potential integral equation (MPIE) for planar structures that can include ferrite layers arbitrarily magnetized. The implementation of the MPIE here reported is carried ...

Fishnet Metamaterials - Rules for Refraction and Limits of Homogenization
(Optical Society of America, 2010)
The perfectly conducting stacked fishnet metamaterial is studied in this paper. The analysis is based on a combination of the mode matching method together with the generalized eigenvalue problem, and takes into account ...

Near-perfect tunneling and amplification of evanescent electromagnetic waves in a waveguide filled by a metamaterial: Theory and experiments
(American Physical Society, 2005)
Amplification of evanescent electromagnetic waves by a metamaterial slab is still a controversial issue. Metallic waveguides operating in cutoff provide a unique physical environment to produce and study these waves because ...

Periodic arrangements of chiral scatterers providing negative refractive index bi-isotropic media
(American Physical Society, 2008)
The main goal of this contribution is to show that periodic arrangements of chiral scatterers can be the basis for the development of three dimensional and isotropic negative refractive index artificial media. Three ...
