Electromagnetic sensors array for the determination of soil condition

To detect soil condition we propose the use of a send/rece ive type of electromagnetic transducer, where the transmitter is a planar coil and the receiver is an arra y of coils with its plane perpendicularly to the transm itter plane. This way, the fields associated with the two coils ar e separated. The use of a layered soil model with paralle l interface planes, for which the forward problem will be solved using the dyadic Green’s functions, is propose d.
