thank you for made available this topic again

hi
your paper is good , but calculation of coupling coefficient values are not matching for your given calculated values how to get those coupling band width values there, plz help me and also external coupling band width , and impedence of the end resonator value , and system impedence values are not having any equation for the calculatio. give me taht inforamtion also
thank you in advance

is ther any suggested book for these round rod combline filters design other than G.L matthaei book if any post the link .
thank you in advance

someone help me.....
i am working on pseudocombline filter?
i dont understand to calculate the quater wavelength λ/4 and the spacing between resonators....

can somebody help me.....
plzzzzzzzzz
