Researchers from Osaka University have developed a high-precision 3D circuit simulator capable of reducing electromagnetic noise. The simulator is in the time-domain necessary for determining the origin of electromagnetic noise as well as quantifying it, making it far easier to reduce the noise for electrical circuits and electronic layouts.
In order to reduce the amount of electromagnetic noise, researchers first had to create a special type of calculation method. This system would allow experts to determine the physical quantities that actually cause electromagnetic noise. They also developed a simulator to allow them to visualize the exact origin of the noise.
Thanks to their efforts, researchers were able to receive a plethora of useful new data. They successfully calculated the simultaneous partial differential integral equation, as well as the variables of current, charge, vector potential, and scalar potential. These all make up the physical quantities of electromagnetic noise and helped researchers to determine the amount of noise found within the 3D conductors that make up the circuit.
This work has allowed researchers to visualize electromagnetic noise in dynamic new ways. With this technology, engineers can now study the behavior of physical quantities in electrical conducting materials, including how they change and propagate over time. The end result is a new ability to determine where electromagnetic noise comes from and why. With this information at their disposal, experts hope to develop a circuit design specially formulated to eliminate electromagnetic noise.
Ultimately, scientists hope their work will help them to achieve the goal of a ‘noiseless’ world, free from the pollution of electromagnetic noise. They believe their work could help to develop equipment that is not only noiseless, but also offers lower power consumption. For now, they are conducting basic and applied research to the problem of electromagnetic noise, and actively searching for partners in the industrial realm to help them realize their vision.
