The method offered does not require any additional assumptions that were used earlier during research work on split-cavities in the form of insertion of conditional metallic walls into the infinite irised waveguide. We demonstrate that all possible eigenfrequencies of the split-cavities can be broken down into two categories: even and odd. For the even types of oscillations the longitudinal electric field is symmetrical relative to the iris, for the odd types --- it is anti-symmetrical. The comparison of the eigenfrequencies obtained via the above method with those taken from literature comes up with a good agreement of the results.</p> </div> </td></tr></table> <table align="center" width="100%" style="margin: 1cm, 0cm, 1cm, 0cm"> <tr><td>&nbsp;</td><td> <table border="0" align="right"> <tr><td><font size="+1">Full text:</font></td> <td align="left" width="50">&nbsp;</td></tr> <tr><td><a href="./pdf/sotnikov.pdf">Sotnikov.pdf (3068K)</a></td> <td>&nbsp;</td> </table> </td></tr> </table> <table align="center" border="0" width="90%"><tr bgcolor="black"><td height="2" style="height:2px"><img src="Picts/pixel_b.gif" alt="" width="90%" height="1" border="0"></td> </tr></table> <div align="center"><a href="index.htm">Back to Contents</a></div> </body> </html>
