Analysis of Electromagnetic Fields and Waves / RSP Bird (PDF)

The Method of Lines (MOL) is a versatile approach to obtaining
numerical solutions to partial differential equations (PDEs) as
they appear in dynamic and static problems. This method, popular in
science and engineering, essentially reduces PDEs to a set of
ordinary differential equations that can be integrated using
standard numerical integration methods. Its significant advantage
is that the analysis algorithms follow the physical wave
propagation and are therefore efficient. This is because the fields
on the discretisation lines are described by generalised
transmission line (GTL) equations. With this formulation we have a
connection to the well known transmission line theory and resulting
in an easy understanding.

The method of lines is a very accurate and powerful way to
analyze electromagnetic waves, enabling a full-wave solution
without the computational burden of pure finite element or finite
difference methods.

With Analysis of Electromagnetic Fields and Waves,
Reinhold Pregla describes an important and powerful method for
analyzing electromagnetic waves. This book:

* Describes the general analysis principles for electromagnetic
fields.

* Includes applications in microwave, millimetre wave and optical
frequency regions.

* Unifies the analysis by introducing generalised transmission
line (GTL) equations for all orthogonal coordinate systems and with
materials of arbitrary anisotropy as a common start point.

* Demonstrates a unique analysis principle with the numerical
stable impedance/admittance transformation and a physical adapted
field transformation concept that is also useful for other
modelling algorithms.

* Includes chapters on Eigenmode calculations for various
waveguides, concatenations and junctions of arbitrary number of
different waveguide sections in complex devices, periodic
structures (e.g. Bragg gratings, meander lines, clystron
resonators, photonic crystals), antennas (e.g. circular and
conformal).

* Enables the reader to solve partial differential equations in
other physical areas by using the described principles.

* Features an accompanying website with program codes in
Matlab for special problems.

Analysis of Electromagnetic Fields and Waves will appeal
to electromagnetic field practitioners in primary and applied
research as well as postgraduate students in the areas of
photonics, micro- and millimetre waves, general electromagnetics,
e.g. microwave integrated circuits, antennas, integrated and fibre
optics, optoelectronics, nanophotonics, microstructures, artificial
materials.
