Green S Function Finite Elements And Microwave Planar Circuits

Green's Function, Finite Elements and Microwave Planar Circuits

The application of Green?s function to planar microwave circuits is now very well accepted as a fundamental tool in electromagnetic analysis. Combining various modern mathematical techniques this book presents comprehensive and detailed methods for numerically describing practical microwave circuits (with one or more ports). Features include: Applications of Green?s function in: planar resonators, gyromagnetic circuits and junction circulators, together with applied examples Detailed explanation of the use of Finite Element Method (FEM) techniques for calculating the solution of planar isotropic and gyromagnetic circuits Specifically written for industrial engineers specialising in the analysis and development of planar circuits and postgraduate researchers A perfect companion text for developing software for the solution of microwave circuits.

Planar Circuits for Microwaves and Lightwaves

Until recently, three principal classes had been known in the electrical cir cuitry. They were as follows: 1) The lumped-constant circuit, which should be called a zero-dimensional circuit, in the sense that the circuit elements are much smaller in size as compared with the wavelength in all three spatial directions. 2) The distributed-constant circuit, which should be called a one-dimensional circuit, in the sense that the circuit elements are much smaller than the wavelength in two directions but comparable to the wavelength in one di rection. 3) The waveguide circuit, which should be called a three-dimensional circuit, in the sense that the circuit elements are comparable to the wavelength in all three directions. The principal subject of this book is the analysis and design (synthesis) theories for another circuit class which appeared in the late 1960s and became common in the 1970s. This new circuit class is 4) the planar circuit, which should be called a two-dimensional circuit, in the sense that the circuit elements are much smaller in size as compared with the wavelength in one direction, but comparable to the wavelength in the other two directions.
