Presentation

SUN Magnetics (Pty) Ltd was established in 2015 as a spin-off from Stellenbosch University and is based in Cape Town, South Africa. They specialise in the development of software tools for the design, simulation, and analysis of superconductor integrated circuits and quantum electronics. Their flagship product, InductEx, provides advanced 3D parameter extraction and layout verification capabilities, including inductance, capacitance, and impedance calculations, compact model extraction, as well as magnetic and gradient field analysis. They also offer JoSIM-Pro, an analogue circuit simulator made specifically for superconductor and quantum circuits with inherent support for superconducting elements, such as the Josephson junction.
Current research includes the use and expansion of these tools to investigate flux trapping as well as flux mitigation in digital superconductor and quantum circuits.
