Book Description
This paper presents an optimisation procedure for the automatic design of frequency selective surfaces. The optimisation tool is based on the genetic algorithm, and embeds an analysis method we recently developed. The implementation of the optimisation code and its application are described, and the major advantages of the method are discussed. An example is also reported, where the code is applied to the optimisation of frequency selective surfaces with circular holes.

Book Description
A Unique, Cutting--Edge Approach to Optical Filter Design With more and more information being transmitted over fiber--optic lines, optical filtering has become crucial to the advanced functionality of today's communications networks. Helping researchers and engineers keep pace with this rapidly evolving technology, this book presents digital processing techniques for optical filter design. This higher--level approach focuses on filter characteristics and enables readers to quickly calculate the filter response as well as tackle larger and more complex filters. The authors incorporate numerous theoretical and experimental results from the literature and discuss applications to a variety of systems--including the new wavelength division multiplexing (WDM) technology, which is fast becoming the preferred method for system upgrade and expansion.

Book Description
This book presents a collection of research articles related to optical filters, commonly used on optical communication systems like the Bragg grating filter, the hybrid Solc filter, the stratified photonic crystal and the two dimensional photonic crystal fiber. These devices were designed and optimized to filter with a high accuracy one or more channels from multiplexed optical signals through the wavelength tenability, which was produced via the thermo-optic, electro-optic and strain effects.

Book Description
Optical Filters play an important role in the areas of imaging, sensing, MEMS and photonics. Omnidirectional Optical Filters gives an integrated presentation of this new type of filter design that is rapidly becoming an integral part of these areas. Not only does the book give the reader a fresh look at the development of optical filter material; it is the first text dedicated to the explanation of omnidirectional optical filters. Beginning with the description of the basic optical phenomena behind these filters, the book moves on to classical filter design, and then newer designs. For the first time, omnidirectional short-pass, band pass, band-blocking and narrow band-pass filter designs are explained in detail. For graduate and undergraduate students interested in optics, photonics and MEMS, this book will give a thorough understanding of the design, fabrication and theory behind omnidirectional optical filters. Engineers in imaging, sensing and MEMS looking to learn more about these filters will also find it a valuable reference and tool.

Book Description
This book presents and discusses strategies for the design and implementation of common-mode suppressed balanced microwave filters, including, narrowband, wideband, and ultra-wideband filters This book examines differential-mode, or balanced, microwave filters by discussing several implementations of practical realizations of these passive components. Topics covered include selective mode suppression, designs based on distributed and semi-lumped approaches, multilayer technologies, defect ground structures, coupled resonators, metamaterials, interference techniques, and substrate integrated waveguides, among others. Divided into five parts, Balanced Microwave Filters begins with an introduction that presents the fundamentals of balanced lines, circuits, and networks. Part 2 covers balanced transmission lines with common-mode noise suppression, including several types of common-mode filters and the application of such filters to enhance common-mode suppression in balanced bandpass filters. Next, Part 3 examines wideband and ultra-wideband (UWB) balanced bandpass filters with intrinsic common-mode suppression. Narrowband and dual-band balanced bandpass filters with intrinsic common-mode suppression are discussed in Part 4. Finally, Part 5 covers other balanced circuits, such as balanced power dividers and combiners, and differential-mode equalizers with common-mode filtering. In addition, the book: Explores a research topic of increasing interest due to the growing demand of balanced transmission lines and circuits in modern communication systems Includes contributions from prominent worldwide experts in the field Provides readers with the necessary knowledge to analyze and synthesize balanced filters and circuits Balanced Microwave Filters is an important text for R&D engineers, professionals, and specialists working on the topic of microwave filters. Post graduate students and Masters students in the field of microwave engineering and wireless communications, especially those involved in courses related to microwave filters, and balanced filters and circuits will also find it to be a vital resource.

Book Description
Three components, gain analysis, tolerance analysis in-depth, and a brief non- linearity analysis, are presented. In the first component, the effects of an Erbium doped waveguide amplifier in a microring are investigated using a time domain simulation. Methods to simulate the gain versus average input signal power in the microring are studied, given that it has a long lifetime compared to the short delay time of the microring. The methods are based on the dependence of the gain on the power of the signal being fed to the ring. An algorithm is proposed to perform a thorough tolerance analysis on any optical circuit with respect to any optical parameter. The algorithm, based on Monte Carlo Simulation, is implemented on a complex optical circuit that is designed to obtain a bandpass filter response of given specifications. It is also tested on similar designs for a comparative study between them. The parameters and the structure of the designs used for the analysis are presented in detail. The results are presented in terms of the yield with respect to the parameter being varied, against their tolerance value. Algorithms for studying the effects of two types of non-linearities are presented. The Kerr nonlinearity and the two-photon absorption are included in the bandpass filter designs used for the tolerance analysis. The algorithms are based on the power circulating in di fferent regions of the circuit under consideration. The variation in the original response because of the loss due to nonlinearity is observed and analyzed for different power levels of the input signal.
