This book is a collection of problems,in which the analysis of a number of microwave
structures of great practical importance. For the first time describes the HFSS Ansoft version 13
software.
HFSS software version 13 is designed for three-dimensional design of microwave devicesand
uses several methods of calculation. At the decision of practical problems, more attention is paid
to the peculiarities of calculation methods and installation of HFSS software options in the course
of constructing three-dimensional models of the waveguide, and microstrip antenna structures.
A number of original heterogeneous structures, filters and contemporary antennas having a linear
and circular polarization analyzed using HFSS. The solution of physical problems associated
with optics, radar, radio physics.
For technical workers, studentsand postgraduate students in the design of microwave
devices and methods for calculating electromagnetic fields in inhomogeneous structures.

introduction
HFSS v. 13 - this is the electromagnetic field calculation program for the
design of microwave structures having multiple calculation algorithms [1]. The
latest version of HFSS software performs calculations using finite element method
in the frequency domain, transient, uses the method of integral equations, as well as
a hybrid approach: the finite element method + method of integral equations.
Each method in HFSS is implemented as a program in which you want to
create a structure under study, set the parameters of materials and calculated
characteristics. After that HFSS generates a mesh for solving the problem of the
finite element method. In HFSS program grid is generated adaptively in dependence
on the characteristics of the structure and characteristics of the field therein.
In HFSS v13 made a big step forward compared to previous versions of the
program, developed by the firm Ansoft. It modifications made mesh generation
algorithms and calculation algorithms. A new fast and stable algorithm generates a
TAU better tetrahedral grids.
Forming a system of equations, providing a mixed order of its units, as well
as decomposition of an arbitrary region solutions, allow implement in
HFSS capabilities high-performance calculation (High-
Performance Computing HPC). The program drawing three-dimensional model has
been improved operations such as insertion and transfer of two-dimensional and
three-dimensional models (imprinting), and the interface has been modified to better
use and automation.
HFSS calculates a wide range of external devices and the parameters of the
microwave antennas, which include electrical and magnetic field, currents, S-
parameters, near- and far-field and can also calculate the transient and time change
of electromagnetic fields [2-4]
Developers can be assured accuracy HFSS when designing devices that
include passive and active being introduced "chips" and simulate thus active
antennas, multilayer microwave integrated circuits, RF / microwave components
and biomedical devices (Fig. B.1, V. 2).

It is also importantthat by HFSS -13 program included a number of examples
that can be used as templates, and which show the new features of the program.
HFSS uses as the main tool for solving electrodynamic problems finite element
method. In this method, the entire volume is divided into tetrahedrons, inside which
the field is represented as a volumetric basis functions with unknown coefficients
which are found by solving the system of linear equations.
In HFSS v13 software module added HFSS-IE, which implements the method
of integral equations, which uses a two-dimensional basis functions describing the
currents on the surfaces, including objects with a finite conductivity, which allows
to describe
