Electromagnetic wave oscillator having multi-tunnel and Electromagnetic wave generating apparatus including the electromagnetic wave oscillator

摘要

An electromagnetic wave generator having multiple tunnels and an electromagnetic wave generator including the electromagnetic wave oscillator, particularly, an electromagnetic wave oscillator for oscillating an electromagnetic wave in a terahertz band, and an electromagnetic wave generator including the electromagnetic wave oscillator. The disclosed electromagnetic wave oscillator includes a waveguide having a folded structure and traveling through electromagnetic waves, an electron beam tunnel passing axially through the folded waveguide and passing the electron beam, and at least one auxiliary tunnel formed around the electron beam tunnel and passing axially through the waveguide; . / RTI
