THz and mmw

The most significant advance in waveguides for the 70-1500 GHz range in half a century

• HE₁₁ Launchers for converting directly from rectangular TE₁₀ to overmoded HE₁₁
• Bi-directional THz couplers for overmoded HE₁₁ with low loss and high directivity
• Low-loss THz miter bends, down-tapers, up-tapers, and polarizers for high-purity overmoded HE₁₁
• Overmoded HE₁₁ eliminates the critical interface issues that have beset traditional THz systems

THz HE₁₁ Launchers for LLWGs

Ultra-Low-Loss HE₁₁ THz Miter Bends
HE11 THz Couplers

A low-loss bidirectional HE₁₁ coupler is being developed with substantially higher directivity than prior HE11 THz couplers for overmoded waveguides operating in the 0.03 to 1.5 THz range.                                   

The novel Laminate-Lined Waveguide (LLWG) is being integrated into a probe for DNP that includes a high-mode THz cavity compatible with MAS and is expected to permit routine lhttps://dotynmr.com/thz-components/laminate-lined-waveguides/ow-cost operation below 15 K.
