In wafer-based and thin-film photovoltaic (PV) devices, the
management of light is a crucial aspect of optimization since
trapping sunlight in active parts of PV devices is essential for
efficient energy conversions. Optical modeling and simulation
enable efficient analysis and optimization of the optical situation
in optoelectronic and PV devices. Optical Modeling and Simulation
of Thin-Film Photovoltaic Devices provides readers with a thorough
guide to performing optical modeling and simulations of thin-film
solar cells and PV modules. It offers insight on examples of
existing optical models, demonstrates the applicability of optical
modeling, and presents concrete directions and solutions for
improving the devices. Along with giving practical hints, the book
highlights significant research, development, and production in the
field. It covers numerous approaches of one-, two-, and
three-dimensional optical modeling, including one-dimensional
semi-coherent modeling and two-dimensional modeling based on the
finite element method (FEM). Many practical examples illustrate the
use of simulations with the developed models, helping readers
better understand and develop their own models as well as
appreciate innovative concepts in light management in thin-film PV
devices.
Speckle study constitutes a multidisciplinary area with inherent
complexities. In order to conquer challenges such as the
variability of samples and sensitive measurements, researchers must
develop a theoretical and statistical understanding of both
biological and non-biological metrology using dynamic speckle
laser. Dynamic Laser Speckle and Applications discusses the main
methodologies used to analyze biospeckle phenomena with a strong
focus on experimentation. After establishing a theoretical
background in both speckle and biospeckle, the book presents the
main methodologies for statistical and image analysis. It then
deals with the concept of frequency decomposition before moving on
to a discussion of fuzzy methods to treat dynamic speckle data. The
book dedicates two sections to applications, including agricultural
approaches. Additional features include photo images of experiments
and software to aid in easy start-up of dynamic speckle usage. A
systematic approach to new dynamic speckle laser phenomena, this
book provides the physical theory and statistical background needed
to analyze images formed by laser illumination in biological and
non-biological samples.

science, biology, and medicine as well as students studying
biomedical physics and engineering, biomedical optics, and
biophotonics.
This book presents how metasurfaces are exploited to develop new
low-cost single sensor based multispectral cameras. Multispectral
cameras extend the concept of conventional colour cameras to
capture images with multiple color bands and with narrow spectral
passbands. Images from a multispectral camera can extract
significant amount of additional information that the human eye or
a normal camera fails to capture and thus have important
applications in precision agriculture, forestry, medicine, object
identifications, and classifications. Conventional multispectral
cameras are made up of multiple image sensors each externally
fitted with a narrow passband wavelength filters, optics and
multiple electronics. The need for multiple sensors for each band
results in a number of problems such as being bulky, power hungry
and suffering from image co-registration problems which in turn
limits their wide usage. The above problems can be eliminated if a
multispectral camera is developed using one single image sensor.

This book gives a comprehensive introduction to Green's function
integral equation methods (GFIEMs) for scattering problems in the
field of nano-optics. First, a brief review is given of the most
important theoretical foundations from electromagnetics, optics,
and scattering theory, including theory of waveguides, Fresnel
reflection, and scattering, extinction, and absorption cross
sections. This is followed by a presentation of different types of
GFIEMs of increasing complexity for one-, two-, and
three-dimensional scattering problems. In GFIEMs, the
electromagnetic field at any position is directly related to the
field at either the inside or the surface of a scattering object
placed in a reference structure. The properties of the reference
structure, and radiating or periodic boundary conditions, are
automatically taken care of via the choice of Green's function.
This book discusses in detail how to solve the integral equations
using either simple or higher-order finite-element-based methods;
how to calculate the relevant Green's function for different
reference structures and choices of boundary conditions; and how to
calculate near-fields, optical cross sections, and the power
emitted by a local source. Solution strategies for large structures
are discussed based on either transfer-matrix-approaches or the
conjugate gradient algorithm combined with the Fast Fourier
Transform. Special attention is given to reducing the computational
problem for three-dimensional structures with cylindrical symmetry
by using cylindrical harmonic expansions. Each presented method is
accompanied by examples from nano-optics, including: resonant metal
nano-particles placed in a homogeneous medium or on a surface or
waveguide; a microstructured gradient-index-lens; the Purcell
effect for an emitter in a photonic crystal; the excitation of
surface plasmon polaritons by second-harmonic generation in a
polymer fiber placed on a thin metal film; and anti-reflective,
broadband absorbing or resonant surface microstructures. Each
presented method is also accompanied by guidelines for software
implementation and exercises. Features Comprehensive introduction
to Green's function integral equation methods for scattering
problems in the field of nano-optics Detailed explanation of how to
discretize and solve integral equations using simple and
higher-order finite-element approaches Solution strategies for
large structures Guidelines for software implementation and
exercises Broad selection of examples of scattering problems in
nano-optics

sensing and image processing researchers, many of whom serve on the
editorial boards of prestigious international journals in these
fields, and are actively involved in international scientific
societies. Providing the reader with a comprehensive picture of the
overall advances and the current cutting-edge developments in the
field of mathematical models for remote sensing image analysis,
