What Is Electromagnetic Field Simulation Software
Electromagnetic field simulation software is software created for solving the fundamental equations governing electromagnetic phenomena. These equations are called Maxwell’s equations.
These days, rather than solving them analytically, it often means solving them with specific physical properties and boundary conditions using numerical solution methods, such as the finite difference time domain method or the finite element method.
Electromagnetic field simulation software includes electrostatic field analysis and electromagnetic field analysis, which deal with electric fields that do not fluctuate with time, and has a variety of applications such as microwave ovens, antennas, and wireless power transmission, not to mention electric motors such as DC motors.
Uses of Electromagnetic Field Simulation Software
Electromagnetic field simulation software is used to study how electromagnetic waves and magnetic forces affect objects. They are used in a wide range of industries, including automotive, space, and defense, but are especially common in manufacturing industries such as electrical and electronic equipment, where it is often used in the design process.
Electromagnetic field simulation software is performed on parts or devices that are subject to electromagnetic waves or magnetic forces, such as supercomputers, laptop computers, microwave ovens, antennas, motors, speakers, and many others.
Characteristics of Electromagnetic Field Simulation Software
The electric and magnetic fields together are called the electromagnetic field, which is created by an electric charge. When a charge is stationary, only an electric field is created, but when the charge moves and an electric current flows, a magnetic field is generated in addition to the electric field. Thus, the electric and magnetic fields are closely related, and Maxwell’s equations express this relationship. Electromagnetic field simulation software is a simulation based on Maxwell’s equations.
There are two major analysis methods: one is the time-domain analysis method, and the other is the frequency-domain analysis method.
The time-domain analysis methods include the finite-difference time-domain method and the transmission line method, while the frequency-domain analysis methods include the finite element method and moments.
The ultimate goal of electromagnetic field simulation software is to know the voltage and current distribution in a circuit or device, or the electromagnetic field near the device or radiated to a distant place. To accomplish this, the model must be created so that results can be obtained in a realistic amount of time, and the analysis must be performed under appropriate computational conditions.
