Abstract

Multi-Frequency EIT has been developed to evaluate the permittivity spectrum of a medium using an improved Howland source. Stray capacitance reduces the output impedance, bandwidth of the data collection leading to erroneous measurements. To address this, we have designed a current source, which uses a novel OCCII - GIC to cancel stray capacitance. The system achieves high output impedance over a 5 MHz frequency range.
