Ultra-thin gold lamellae drastically amplify the incoming terahertz pulses (red) in the underlying graphene layer, enabling efficient frequency multiplication. Credit: HZDR/Werkstatt X On the electromagnetic spectrum, terahertz light is located between infrared radiation and microwaves. It holds enormous potential for tomorrow’s technologies: Among other things, it might succeed 5G by […]

Switching points of the brain are simulated with magnetic waves, which are specifically generated and divided using nonlinear processes within microscopically small vortex discs. Credit: HZDR/Sahneweiß/H. Schultheiß Neural networks are some of the most important tools in artificial intelligence (AI): they mimic the operation of the human brain and can […]
