Gómez-Correa JE, Balderas-Mata SE, Garza-Rivera A, Jaimes-Nájera A, Trevino JP, Coello V, Rogel-Salazar J, Chávez-Cerda Set al., 2019, Mathematical physics of propagating modes in planar waveguides, Revista Mexicana de Fisica E, Vol: 65, Pages: 218-222, ISSN: 1870-3542

© 2019 Sociedad Mexicana de Fisica. All rights reserved. In this paper, we present a detailed physical analysis of the formation of the propagation transverse modes in planar dielectric waveguides using a mathematical-physics approach. We demonstrate physically that, at the wavelength scale, the pure stationary mode inside planar waveguide is described by the cosine function. Meanwhile, the sine function arises from the interference of waves that superpose with a relative phase shift e-ip, yielding a quasi-stationary periodic mode.

Rogel-Salazar J, 2018, Data science and analytics with python, ISBN: 9781498742092

© 2017 by Taylor & Francis Group, LLC. Data Science and Analytics with Python is designed for practitioners in data science and data analytics in both academic and business environments. The aim is to present the reader with the main concepts used in data science using tools developed in Python, such as SciKit-learn, Pandas, Numpy, and others. The use of Python is of particular interest, given its recent popularity in the data science community. The book can be used by seasoned programmers and newcomers alike. The book is organized in a way that individual chapters are sufficiently independent from each other so that the reader is comfortable using the contents as a reference. The book discusses what data science and analytics are, from the point of view of the process and results obtained. Important features of Python are also covered, including a Python primer. The basic elements of machine learning, pattern recognition, and artificial intelligence that underpin the algorithms and implementations used in the rest of the book also appear in the first part of the book. Regression analysis using Python, clustering techniques, and classification algorithms are covered in the second part of the book. Hierarchical clustering, decision trees, and ensemble techniques are also explored, along with dimensionality reduction techniques and recommendation systems. The support vector machine algorithm and the Kernel trick are discussed in the last part of the book.

Rogel-Salazar J, 2014, Essential MATLAB® and octave, ISBN: 9781482234664

© 2015 by Taylor & Francis Group, LLC. Learn Two Popular Programming Languages in a Single Volume Widely used by scientists and engineers, well-established MATLAB® and open-source Octave are similar software programs providing excellent capabilities for data analysis, visualization, and more. By means of straightforward explanations and examples from different areas in mathematics, engineering, finance, and physics, Essential MATLAB and Octave explains how MATLAB and Octave are powerful tools applicable to a variety of problems. This text provides an introduction that reveals basic structures and syntax, demonstrates the use of functions and procedures, outlines availability in various platforms, and highlights the most important elements for both programs. Effectively Implement Models and Prototypes Using Computational Models This text requires no prior knowledge. Self-contained, it allows the reader to use the material whenever needed rather than follow a particular order. Compatible with both languages, the book material incorporates commands and structures that allow the reader to gain a greater awareness of MATLAB and Octave, write their own code, and implement their scripts and programs within a variety of applicable fields. It is always made clear when particular examples apply only to MATLAB or only to Octave, allowing the book to be used flexibly depending on readers’ requirements. Includes brief, simple code that works in both MATLAB and Octave Provides exercise sections at the end of each chapter Introduces framed examples and discussions with a scientific twist Exercises are provided at the end of each chapter Essential MATLAB and Octave offers an introductory course in MATLAB and Octave programming and is an authoritative resource for students in physics, mathematics, statistics, engineering, and any other subjects that require the use of computers to solve numerical problems.

Rogel-Salazar J, Treviño JP, Chávez-Cerda S, 2014, Engineering structured light with optical vortices, J. Opt. Soc. Am. B, Vol: 31, Pages: A46-A50

In this work, we demonstrate the possibility of generating and controlling any given kind of structured radially symmetric intensity profile with an embedded optical vortex. This is achieved with the use of Sturm–Liouville theory on a circular domain with Bessel, Laguerre–Gauss, Zernike, and Fourier bases. We show that the core in- tensity profile can be constructed independently of the topological charge of the vortex. © 2014 Optical Society of America

Conference paper

Tsangaris CL, New GHC, Rogel-Salazar J, 2003, Unstable Bessel beam resonator

We propose an unstable laser resonator design consisting of a conical and a convex mirror. The intensity profile of its lowest order mode resembles a Bessel function with little inherent modulation imposed by the geometry. © 2003 IEEE.
