Can anyone tell me the cut-off wavelength of dielectric filled waveguide?

I guess cut-off frequency of regular wave guide, divided by square root (Er).
O.K., it's not only multiplying the wavelength with √Er, you also have to put in the reduction factor for width and height when calculating the cut-off frequency. But in case of a completely filled waveguide, it's just a geometry factor.Also depends on a particular mode.
