XBa(Mg1/3Ta2/3)O3-(1-x)Ba(Mg 1/3 Nb2/3)O3 (xBMT-(1-x)BMN) ceramics were studied by FTIR spectroscopy. The normal modes were assigned by investigating the frequency shift versus Ta concentration. The frequency shifts of the normal modes of the O layers and that of the Ta/Nb layers explained the linear decrease of microwave dielectric constant.
