Size of a waveguide for a given wavelength

    Let λ be the wavelength of an EM wave in empty space.
    Let a x 0.5*a be the dimensions of the cross-section of the waveguide.
    Can I use a = 0.35*λ ?
    It should be possible, it corresponds to θ = π/4, where θ is the effective
    angle between the long axis of the waveguide and the direction of propagation
    of an approximately plane wave.
