Abstract

PURPOSE:To reduce attenuation, by making the electromagnetic field at guide wall small, periodically changing the guide diameter in the direction of guide axis, and changing the area of aperture of energizing electromagnetic horn of multimode waveguide so that the phase speed of each mode can be equal to the light speed. CONSTITUTION:The section of the input section A consists of the aperture of the electromagnetic cone horn 2 and the conductor plate, and the surface component of the electric field shows the same distribution as the main waves at the aperture of the horn 2 and it is zero at the conductor surface according to the boundary condition. The distribution in the section is a little distored since all the modes are propagated in the light speed, but they are propagates axially with almost the same sectional distribution. The sectional component of the electromagnetic field near the guide wall is very little. It is smaller when the area of the electromagnetic horn 2 for energizing is smaller, and the axial component of the magnetic field is negligibly small for the spherical waveguide to the sectional component. Thus, the attenuation can be made the same as or lower than the attenuation of the magnetic type axial mode of the circular type waveguide 1.
