TODO - A numerical code (PERIODIC HYBRID) is developed for the calculation of
the dispersion relation, the electromagnetic field components, and the
quality factor of a dielectrically loaded, periodically corrugated
gyrotron beam tunnel. The Floquet theorem is used to express the fields
in the vacuum region, and an eigenfunction expansion is employed in each
dielectric indentation. The boundary conditions imposed at the interface
lead to a linear system of equations, which is appropriately truncated
for the numerical implementation. The code has been benchmarked, and the
results have been interpreted as the product of coupling between cavity
and waveguide modes.
