Decoupled STNO and HBAR module: (a) Modular modeling of transport and magnetization dynamics of the STNO. (b) Simulated FFT spectrums of a free running STNO at T = 300 K and T = 0 K (noiseless) for V tune = 23 mV, showing the fundamental mode and harmonics. (c) Tunability of a free running STNO with \({\overrightarrow{H}}_{ext}\) and V tune . (d) Equivalent circuit model for the HBAR where each acoustic mode is modeled as a separate RLC circuit. (e) Admittance plots of a single mode resonator (FBAR) and a 2-port HBAR filter, consistent with the Equation (8). HBAR has multiple high Q resonance peaks that are spaced by Δf = 43 MHz depending on the substrate thickness.
