In this paper, the effect of the slot distance, existed between the two parts of BCI-probe shield, on its performance is studied, therefore, two ferrite materials with the same size and different characteristics are used to implement two identical BCI-probes. The input impedance and reflection coefficient are measured for four different values of slot distance 0.5, 1, 2 and 3 mm. Practical results show a notable effect of the slot distance on measured quantities. Measured impedance analysis shows the appearance of three capacitive regions in its spectra, therefore, a three dimensional electromagnetic (EM) model is implemented in CST-Microwave Studio (MWS) software to disclose the main source parameters responsible for it. Results of achieved study, using developed EM model, were in accordance with measured data for the implemented prototypes, and showed the same resonance phenomena.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
