# HFWorks

HFWorks is a complete 3-Dimensional field simulator for RF/Microwave and Wireless applications, based on the powerful finite element method. Currently, this microwave design and antenna pattern software is the only high frequency electromagnetic Add-in to SOLIDWORKS.

HFWorks is Gold Certified by SolidWorks® Corporation, and it is fully embedded in the software so you won’t have to toggle between programs or deal with various formats. The HFWorks microwave design software includes three main solvers: Antennas, S-parameters, and Resonance.

## S-Parameters

Scattering parameters or S-parameters (the elements of a scattering matrix or S-matrix) describe the electrical behaviours of linear electrical networks when undergoing various steady state stimuli by electrical signals. Although applicable at any frequency, S-parameters are mostly used for networks operating at radio frequency and microwave frequencies where signal power and energy considerations are more easily quantified than currents and voltages.S-parameters change with the frequency are readily represented in matrix form and obey the rules of matrix algebra.

## Resonance

Resonance is the tendency of a system to oscillate with larger amplitude at some frequencies than at others. These are known as the system’s resonant frequencies. At these frequencies, even small periodic driving forces can produce large amplitude oscillations, because the system stores energy. When loss is small, the resonant frequency is approximately equal to a natural frequency of the system, which is a frequency of unforced vibrations. Some systems have multiple, distinct, resonant frequencies. Resonance phenomena occur with all types of waves: there is mechanical resonance, acoustic resonance, electromagnetic resonance, nuclear magnetic resonance, electron spin resonance and resonance of quantum wave functions.

## Antennas

An antenna is a transducer that transmits or receives electromagnetic waves. In other words, antennas convert electromagnetic radiation into electric current, or vice versa. Antennas generally deal in the transmission and reception of radio waves, and are a necessary part of all radio equipment. Antennas are used in systems such as radio and television broadcasting, point-to-point radio communication, wireless LAN, cell phones, radar, and spacecraft communication.
