Electromagnetic Simulations
Overview
Electromagnetic simulations are computer-based analyses that use mathematical models to predict the behavior of electromagnetic fields in a given system. These simulations are used to study a wide range of phenomena, including the propagation of electromagnetic waves, the interaction of electromagnetic fields with matter, and the performance of electromagnetic devices such as antennas, transmission lines, and electrical machines.
Some of the most common methods we use are the finite-difference time-domain (FDTD) method, the finite-element method (FEM), and the boundary element method (BEM). Each of these methods has its own advantages and disadvantages, and the choice of which method to use depends on the specific problem being studied and the desired level of accuracy and detail.
Some examples of applications of electromagnetic simulations include the design and optimization of antennas for wireless communication, the analysis of the electromagnetic compatibility of electronic systems, and the prediction of the performance of electric power transmission systems. Electromagnetic simulations are also used to study the interaction of electromagnetic fields with biological systems and to assess the potential health impacts of exposure to electromagnetic fields.
DV Research provides simulation services in the following applications
Wireless communication: Electromagnetic simulations are used to design and optimize antennas for wireless communication systems. This involves predicting the radiation pattern and gain of the antenna, as well as its performance in various environments and under different operating conditions.
Electronic systems: Electromagnetic simulations are used to assess the electromagnetic compatibility (EMC) of electronic systems, which is the ability of a system to function properly in the presence of electromagnetic interference (EMI) from other sources. This is important because EMI causes malfunctions or disruptions in the operation of electronic devices.
Electric power transmission: Electromagnetic simulations are used to predict the performance of electric power transmission systems, including the transmission of electrical energy over long distances through high-voltage transmission lines. This involves simulating the behavior of the electrical and magnetic fields in the transmission lines, as well as the power flow through the system.
Electromagnetic field interactions with biological systems: Electromagnetic simulations are used to study the interaction of electromagnetic fields with biological systems, including the potential health impacts of exposure to electromagnetic fields. This involves simulating the absorption of electromagnetic energy by different tissues in the body and predicting the resulting temperature rise and other biological effects.
Electromagnetic devices: Electromagnetic simulations are used to design and optimize a wide range of electromagnetic devices, including antennas, transmission lines, electrical machines, and other devices that use or generate electromagnetic fields.
