A pair of Nebraskan engineers have devised a cost-effective way to make concrete that can shield electronics from EMP waves, effectively turning the tide on cybernetic and electronic warfare.
Engineers Christopher Tuan and Lim Nguyen have developed what they call conductive concrete which, when put together, could build structures strong enough to protect electronics from EMP.
Their technology is ready for commercialization, and the University of Nebraska-Lincoln has signed an agreement to license the technology to American Business Continuity Group LLC. They are developers of disaster-resistant structures.
It can be understood that electromagnetic energy travels in waves and spans a wide spectrum. Its presence everywhere meant it can appear as sunlight, radio waves, microwaves and even X-rays. However, an attack from a pulse of electromagnetic energy can cripple electronic systems. This can potentialy pose a threat to national security and critical infrastructure such as power grids and data centers.
Tuan explained that EMP is very lethal to electronic equipment. However, they have found a key ingredient that "dissipates" wave energy. This technology can offer a lot of new potential to the construction industry. The pair first developed their patented conductive concrete to melt snow and ice from surfaces, such as roadways and bridges. However, they also discovered another quality - block electromagnetic energy.
This works by absorbing and reflecting EM waves. They replaced standard concerete aggregates with magnetite, a mineral that absorbs microwaves like a sponge. Their recipe includes carbon and other metal components that can absorb and reflect the EM waves. The end-product is more cost-effective and flexible than other hsielding methods.
A prototype in Lakeland, Florida has allowed a structure to exceed military shielding requirements. The concrete has the ability to provide a multi-threat structure. Meaning, it's able to withstand an attack either by explosives or via EMP.
The pair will continue to investigate more uses for their conductive concrete, including improvements for de-icing and radiant heating, as well as anti-static flooring applications.
