Surface solitons in chirped photonic lattices
(2007)
We study surface modes at the edge of a semi-infinite chirped photonic lattice in the framework of an effective discrete nonlinear model. We demonstrate that the lattice chirp can change dramatically the conditions for the ...
Spatially localized modes in two-dimensional chirped photonic lattices
(AMER PHYSICAL SOC, 2008-05)
We numerically study both linear and nonlinear surface modes in semi-infinite chirped two-dimensional photonic lattices in the framework of an effective discrete nonlinear model. We demonstrate that the lattice chirp can ...
Chirp-wave expansion of the electron wavefunctions in atoms
(2014)
The description of the electron wavefunctions in atoms is generalized to the fractional Fourier series. This method introduces a continuous and infinite number of chirp basis sets with linear variation of the frequency to ...

Limiares auditivos eletrofisiológicos com os estímulos NB CE-Chirp® LS e NB iChirp no público infantil
(Universidade Federal de Santa MariaBrasilFonoaudiologiaUFSMPrograma de Pós-Graduação em Distúrbios da Comunicação HumanaCentro de Ciências da Saúde, 2022-03-23)
The present research described reference values for the electrophysiological thresholds of the frequency specific Auditory Brainstem Response (ABR) with the NB CE-Chirp® LS and NB iChirp stimuli in hearing infants and ...
Development and analysis of a model based on chirped fiber Bragg gratings employed for cracks characterization in materials
(Elsevier Science, 2018-11)
In this work a model was developed that allows to understand the behavior of a chirped fiber Bragg grating for the detection and characterization of cracks in materials. In addition to the amplitude response, we show that ...
