Shape of the TE01 to TE11 mode converter showing the displacement of the axis versus length. The maximum displacement of the axis is 4.7 mm over the 0.65 m converter, which has a diameter of 31.5 mm.
Calculated mode conversion along the curvilinear path length z. The conversion from TE01 to TE11 is 97%. The excitation of some of the undesirable modes is also illustrated. The modes included in the calculation are the TE11, TE01, TE12, TE21, TM01, TM11, TM02, and TM21.
The TE01 to TE11 mode converter prior to assembly into the new injection system of VENUS.
Calculated power distribution for the HE11 mode in W/m2 across the circular waveguide assuming a total power of 1 W in the waveguide.
The new injection assembly incorporates the 28 GHz mode converters. The large diameter aperture on the plasma screen shown in the lower left corner is the launch point of the 28 GHz in the HE11 mode. The smaller rectangular opening is to launch the 18 GHz microwave power.
Chebyshev coefficients for the mode converter.
