The paper presents an approach to estimate the range of location of the first natural frequencies of corrugated structures. It needs the knowledge of the solution of simple equations instead of the more complicated characteristic equation for the corrugated structure. Inverted and noninverted magnetron cavities are considered as examples. It is shown that not only the location of the frequencies but also the general properties of the eigenmode fields can be predicted based on an analysis of geometrical properties of the simplified characteristic equation of the structure which is carried out in terms of zeros and poles of the rigorous characteristic equation.
