Terahertz and sub-terahertz communications move from theory to proof | Electronics360

Terahertz frequencies were written off as a communication dead zone — now engineers are proving that the "inhospitable spectrum" label was a failure of imagination, not physics.

Theory Briefing
- Terahertz and sub-terahertz bands were long dismissed as impractical for communications due to extreme atmospheric absorption and hardware limits.
- New proof-of-concept demonstrations show real data transmission at these frequencies, challenging the scientific consensus that once defined them as unusable.
- This shift mirrors a classic paradigm shift pattern — incremental engineering breakthroughs quietly dissolving a theoretical boundary the field assumed was fixed.
