Achieving Ultra-Broad Microwave Absorption Bandwidth Around Millimeter-Wave Atmospheric Window Through an Intentional Manipulation on Multi-Magnetic Resonance Behavior

The frequency and intensity of multi-magnetic resonance are freely regulated by co-doping La 3+ and Zr 4+ ions. Zr 4+ occupation is elaborately modified for promoting the portion of polarization/conduction loss to increase profoundly. The optimized electromagnetic characteristics lead to an ultra-wide bandwidth of 12.5+ GHz around millimeter-wave atmospheric window.
