- Abstract
- This paper shows the microwave properties of a magnetic nanowired substrate studied in a microstrip line configuration. The ferromagnetic resonance (FMR) properties are investigated using a scalar network analyzer (SNA) in the frequency range from 100 MHz to 40 GHz and under a static magnetic field up to 10 kOe. The FMR properties extracted from measurements are in very good agreement with those expected for the classical FMR theory. At the FMR frequency, the microwave energy transported by the electromagnetic wave propagating inside the microstrip, is completely absorbed. Absorption phenomena have been observed in the presence but also in the absence of the DC magnetic field. The application of such a DC field is necessary for classical ferrites but not suitable for compact devices. Hence, a magnetic nanowired substrate is a good choice for designing microwave planar devices such as stopband filters, attenuators, and thin magnetic field sensors.
