ANSYS HFSS TOOL
ANSYS HFSS (High Frequency Structure Simulator) offers multiple state-of-the-art high-frequency
electromagnetic solvers. These powerful tools are based on the highly accurate and reliable finite
element method (FEM), the large scale method of moments technique, and ultra-large scale asymptotic
methods of physical optics (PO) and shooting and bouncing rays (SBR). When combined with ANSYS HPC
technology, rigorous multi-solver hybrid techniques deliver advanced multi-scale, multi-fidelity
computational electromagnetics available in an easy-to-use design environment.
In physics and electrical engineering, a conductor is an object or type of material that allows the flow
of an electrical current in one or more directions. A metal wire is a common electrical conductor.
Electrical current is generated by the flow of negatively charged electrons, positively charged holes, and
positive or negative ions in some cases.
Pure elemental silver is the best electrical conductor encountered in everyday life.
Copper, steel, gold, aluminum, and brass are also good conductors. In electrical and electronic
systems, all conductors comprise solid metals molded into wires or etched onto circuit boards.
Some liquids are good electrical conductors. Mercury is an excellent example. A saturated saltwater solution acts as a fair conductor. Gases are normally poor conductors because the atoms
are too far apart to allow a free exchange of electrons. However, if a sample of gas contains a
significant number of ions, it can act as a fair conductor.
A dielectric material is a substance that is a poor conductor of electricity, but an efficient supporter of
electrostatic fields. If the flow of current between opposite electric charge poles is kept to a minimum
while the electrostatic lines of flux are not impeded or interrupted, an electrostatic field can store
energy. This property is useful in capacitors, especially at radio frequencies. Dielectric materials are also
used in the construction of radio-frequency transmission lines.
