This article presents a novel way to estimate magnetodielectric composites’ complex permittivity ($\varepsilon $) and permeability ($\mu$). A methodology based on artificial neural network (ANN) modeling is proposed to determine$\varepsilon $and$\mu$from$S$-parameter measurements around 2.45 GHz, obtained using a new microstrip split ring resonator (SRR)-based resonant sensor.
