What are computational techniques in electromagnetics?
Computational electromagnetics consists mainly of two classes of numerical solvers: one that solves differential equations directly, the differential-equation solvers; and one that solves integral equations, the integral equation solvers.
Both these classes of equations are derived from Maxwell's equations..
What are the applications of computational electromagnetics?
It can be applied in many areas of engineering and science including fluid mechanics, acoustics, electromagnetics, fracture mechanics, and plasticity..
What is the computational electromagnetics method of moments?
The method of moments (MoM) is a full-wave numerical method that discretizes the integral equation(s) of electromagnetic fields.
Since the integral equation satisfies the Sommerfeld radiation condition automatically, MoM is especially suitable for solving open problems, such as scattering and radiation problems..
What is the difference between FEM and MoM?
Method of Moments and Finite Element Methods are two of the most used methods in computational electromagnetics to solve electromagnetic equations.
As it is known, in FEM sparse matrixes are used while MoM uses the full-matrixes..
What is the finite integration technique in electromagnetics?
The Finite Integration Technique (FIT) is a consistent discretization scheme for Maxwell's equations in their integral form.
The resulting matrix equations of the discretized fields can be used for efficient numerical simulations on modern computers..
What is the use of computational electromagnetics?
This makes computational electromagnetics (CEM) important to the design, and modeling of antenna, radar, satellite and other communication systems, nanophotonic devices and high speed silicon electronics, medical imaging, cell-phone antenna design, among other applications..
Why do we need to study electromagnetics?
It is the foundation for the technologies of electrical and computer engineering, spanning the entire electromagnetic spectrum, from DC to light waves, from electromechanic technologies to microwaves, antennas and photonics..
Why do we need to use numerical methods in electromagnetics?
Numerical methods are developed to study various applications in electromagnetic wave propagation and scattering.
Analytical methods are used where possible to enhance the efficiency, accuracy, and applicability of the numerical methods..
- Electromagnetism also plays a crucial role in modern technology: electrical energy production, transformation and distribution; light, heat, and sound production and detection; fiber optic and wireless communication; sensors; computation; electrolysis; electroplating; and mechanical motors and actuators.
- The Lorentz law, one of the fundamental laws in electromagnetic analysis, describes the force that one charge with velocity v and electric quantity Q is subjected to electric field E and magnetic field B.
From: The Inclusion-Based Boundary Element Method (iBEM), 2022. - The method of moments (MoM) is a full-wave numerical method that discretizes the integral equation(s) of electromagnetic fields.
Since the integral equation satisfies the Sommerfeld radiation condition automatically, MoM is especially suitable for solving open problems, such as scattering and radiation problems.
