  Recently, it was shown, that the absence of circular polarization of visible
light from quasars, severely constrains the interpretation of axion like
particles (ALPs) as a solution for the generation of the linear polarization.
Furthermore, the new observation of the linear polarization in the radio
wavelength from quasars, similar to the earlier observation performed in the
optical band, makes the ALPs scenario inconsistent with at least one of the two
observations. In this study we extend this scenario, to two axion like
particles, one scalar and another pseudoscalar. We find, that the effects from
scalar and pseudoscalar cancel out each other, thereby suppressing the circular
polarization, while preserving consistent linear polarization, as observed in
both visible and radio waves bands.
