We have shown that the thermal emission of the amorphous dust composed of amorphous silicate dust (a-Si) and amorphous carbon dust (a-C) provides excellent fit both to the observed intensity and the polarization spectra of molecular clouds. The anomalous microwave emission (AME) originates from the resonance transition of the two-level systems (TLS) attributed to the a-C with an almost spherical shape. On the other hand, the observed polarized emission in submillimeter wavebands is coming from…
