corrugated waveguide

hey there

i have the following model. the sidewall of the waveguide are representation of the equation

a*delta*sin((2*pi/lambda)*_u) , a+a*delta*sin((2*pi/lambda)*_u+theta) , where a = 7.5cm , lambda = 6.708 cm , theta and delta are varied (delta 0.01-0.1 ,theta 0-pi).

the problem is when the value of delta between 0.01-0.05 the S11 isn't convenient also when the value of delta between 0.06-0.1 it only convenient when the value of theta is pi.

the boundary condition are assigned to be finite conductive.

the figures shows 2 output for delta equal 0.08 and 0.05.

is there any thing that i miss.
