MultiFields is a unique engineering tool that can solve any
electromagnetic problem involving a network of arbitrarily oriented
aboveground and buried conductors energized by any number of current
and voltage sources. MultiFields is a dream come true for those who
have to tackle complex electromagnetic problems involving conductor
networks. MultiFields is probably the only EMF software that can
provide accurate solutions to transient and steady-state problems in
the frequency range of 0 to thousands of megahertz. The central
components of MultiFields are the HIFREQ, MALZ, and FFTSES
MultiFields tackles the Most Challenging Electromagnetic Problems
MultiFields calculates the scalar potential, and the electric and
magnetic fields due to an energized conductor network, as well as
the current distribution in the conductors. MultiFields was designed
to solve problems accurately, without ignoring soil characteristics,
conductors in the soil, or nonenergized metallic structures in air
or soil. With MultiFields you can:
Study transients (such as lightning, switching surges and any
conceivable surge problem) and high frequency disturbances on
power system networks, structures and grounding systems at
frequencies ranging from a few hertz to hundreds of megahertz...
Calculate current and potential distributions in all conductors,
EMF values in air and soil and voltages along well defined paths
due to buried or in-air power system conductors and structures.
Calculate electromagnetic interference to pipelines,
communication lines, etc.,in one single step. Inductive,
capacitive and conductive effects are accounted for
Analyze cathodic protection problems and optimize rectifier
capacities and locations on protected structures extending up to
hundreds of km.
Use FFTSES, a fully integrated and automated Fourier Transform
tool, to visualize electroma-gnetic fields in the time domain.
Study re-radiation interference or calculate current
distributions in monopole, quarter-wave, and other antenna
structures excited at frequencies reaching hundreds of
Calculate induction between arbitrary circuits at low and high
frequencies and during surge conditions. Determine self and
mutual impedances as well as capacitances of these circuits
whether they located above or below ground!
