Calabazas Creek Research, Inc. designs mode converters and tapers for a number of applications, including accelerator systems, Radar, and fusion devices. Recent converters include:

• TE11 to TE01
• TE11 to TE12
• TE01 to 80% TE01 and 20% TE02 for transmission across waveguide gaps
  

Tapers are designed to maximize mode purity while minimizing length. Nonlinear tapers are designed using the optimizing feature in Cascade to achieve mode purities exceeding 98%.

TE11 to TE12 Mode Converter/Taper

This device converts the TE11 mode to the TE12 mode and increases the waveguide diameter from 1.5 inches to 4.75 inches. At the same time, the device transmits the TE01 mode without modification. This converter/taper will be used in the RF waveguide system for the Next Linear Collider.
