represent outside row ripple, edge
direction is circle symmetrical structure, then wave function form is:
At z=0 and z=b place, wave function meets boundary condition:
Can obtain TM mould wave function expression formula is thus:
In formula, m, n=0,1,2,
During distance b< λ/2 between the upper and lower metallic plate of radial waveguide, in radial waveguide, the lowest mode of ripple transmission is TM
00mould, is called the main mould of radial waveguide.The main mould TM of radial waveguide can be obtained by the solution of above TM ripple
00the field distribution of mould is:
The TM of radial waveguide
00mould electric field only has z to component, and the circumferentially electric field identical at radius is identical; Magnetic field only has
to component, at the circumferentially magnetic field equal and opposite in direction that radius is identical, direction is circumferentially tangential; Radial waveguide surface only has radial surface current.TM
00if mould is benchmark with the direction of propagation, then claim TEM
(r)mould, r is that the direction of propagation is namely radial, elect magnetic field both without r to electric field component, also without r to magnetic to component, be cylinder TEM mould.TM
00the Electric and magnetic fields of mould all with Z,
irrelevant, be only the function of radial distance.As can be seen here, the physical structure of radial waveguide and field distribution are all radially symmetrical, are conducive to constant amplitude homophase when guaranteed output distribution and power combing.
