Microwave Circuit Modeling Using Electromagnetic Field Simulation

This book is about modeling microwave circuits using commercial electromagnetic field-solvers. But before we can model a circuit we have to understand how the tools work. All the field-solvers we will discuss are based on well-established numerical methods for solving Maxwell’s equations. We have tried to gather just enough background material on the major numerical methods to help the reader appreciate what is going on behind the interface. We will spend a lot of effort outlining the strengths and weaknesses of each numerical method in a fair and balanced way. This knowledge helps us choose the right software tool for a specific task and set up the problem more intelligently. I have included some, but not a lot of information on simulation times. I am not interested in benchmarking various tools against each other because that borders on marketing. When I do quote times it is mostly for historical reasons and to point out how far we have come in only a decade. I may also quote simulation times to
emphasize the difference between a lossless and a lossy analysis. Given the right problem and an intelligently constructed model, all of the software packages will give a usable answer in a reasonable amount of time. All the factors we have to consider when constructing that model is what this book is about.
