      abstract     = {In recent years the generation of high power millimeter
                      wave and Terahertz radiation has progressed substantially,
                      enabling electron beam manipulation and acceleration in
                      structures with a footprint of several centimeters. However,
                      in many experiments the external driving pulse is coupled
                      collinearly into the waveguide structure which increases the
                      coupling footprint relative to the wavelength
                      tremendously(≈30 𝜆 or more) in comparison to
                      conventional structures(≈1 𝜆 or less). Here, the design
                      of a double-bend mode con-verter for 300 GHz is presented
                      which converts the fundamental TE11 mode
                      quasi-instantaneously to the TM01 mode for the accelerating
                      structure. In comparison to an s-shaped converter, the
                      present design makes an additional waveguide bend obsolete.
                      The structure length along the beam axis is only 4 mm (4
                      𝜆), showing a major advance in compactness. Combined with
                      a horn antenna for free-space to waveguide coupling, the
                      maximum power coupled into the structure reaches 83 $\%,$
                      while the collinear scheme does not exceed 74 $\%.$},
