Momentum Press is proud to bring to you Chemical Sensors: Simulation and Modeling Volume 4: Optical Sensors, edited by Ghenadii Korotcenkov. This is the fourth of a new multi-volume comprehensive reference work that provides computer simulation and modeling techniques in various fields of chemical sensing and the important applications for chemical sensing such as bulk and surface diffusion, adsorption, surface reactions, sintering, conductivity, mass transport, and interphase interactions. In this fourth volume, you will find background and guidance on: * Approaches used for modeling and simulation of various types of optical sensors such as fiber optic, surface plasmon resonance, Fabry-Perot interferometers, transmittance in the midinfrared region, luminescence-based devices, and more * Approaches used for design and optimization of optical systems aimed for both remote gas sensing and gas analysis chambers for the nondispersive infrared (NDIR) spectral range * Multiscale atomistic simulation of hierarchical nanostructured materials for optical chemical sensing Chemical sensors are integral to the automation of myriad industrial processes and everyday monitoring of such activities as public safety, engine performance, medical therapeutics, and many more. This multi-volume reference work covering simulation and modeling will serve as the perfect complement to Momentum Press’s 6-volume reference work, Chemical Sensors: Fundamentals of Sensing Materials and Chemical Sensors: Comprehensive Sensor Technologies, which present detailed information related to materials, technologies, construction, and application of various devices for chemical sensing. Each simulation and modeling volume in the present series reviews modeling principles and approaches peculiar to specific groups of materials and devices applied for chemical sensing.
