Electromagnetic compatibility (EMC) connectors are primarily used in military, aerospace, and industrial applications to provide enhanced protection from electromagnetic interference (EMI). Power and signal connections must have access to the system. Those access points can be weak links in EMC performance. EMC connectors and cabling systems often have features like enhanced shielding, EMI gaskets, cable […]

How can EMI be weaponized?
Electromagnetic interference (EMI) can be an unwanted and disruptive aspect of electronic system designs. It can also be amplified and weaponized. EMI is being weaponized in purpose-built high-power microwave (HPM) tactical systems that devastate electronics without the side effects of physical destruction. The initial weapons have been deployed, and a roadmap has been outlined for […]
How can power converters be designed to minimize EMI?
Switch-mode power converters are highly efficient and cost-effective devices. However, they must be carefully designed and integrated into systems to avoid electromagnetic interference (EMI) problems. This article reviews some EMI sources in power converters and examines a few design considerations for DC/DC converters and DC/AC inverters in power conversion, renewable energy, and motor drive applications. […]
Controlling EMI and improving sustainability
Optimized designs require less electromagnetic interference (EMI) shielding and other materials, improving sustainability. Improved EMI performance extends system life and reduces e-waste, further enhancing sustainability. More sustainable shielding materials are being developed for use when shielding is required. This article reviews the basics of EMI, examines common shielding materials to provide a baseline for comparing […]
