UK-based EMC company acquired

Nolato acquired UK-based P&P Technology in spring 2023. The company, based in ­Maldon, Essex, northeast of London, provides component- and materials-based ­electronics shielding solutions to ensure electromagnetic compatibility (EMC).


What happens when an electromagnetic wave strikes a metallic barrier?

For those who require this question answered with higher mathematical equations, electromagnetic theory is well documented from a multitude of sources, in varying degrees of detail and mathematical content! Read more here.


How can EMI be contained?

In simple terms, most ‘shielding’ problems could be solved by welding the equipment into seamless steel box. The problems that this would lead to are obvious, access would be impossible, power unavailable, visibility would be zero and the equipment would rapidly overheat.
