eg, consider WiFi. They choose their bands carefully for wireless standards, and terahertz is pretty far from microwave GHz. I've never seen direct THz synthesis outside of partially-insane radar engineers.

I thought half the controversial scanners since 9/11 were THz (the other half being backscatter X-ray)? Was that just a marketing term?

(I can easily imagine "terahertz for terrorism" being a slogan…)
