The composite scattering between dielectric sea surface and a conducting plate above it is calculated by using Physical Optical method and reciprocity theorem.

The common capacitance sensor is composed of two-electrode planks which vary in shape and can be fixed in different plane of space. The driving and inductive electrode pole placed in the same plane of the uniplanar scattering-field capacitive sensor. The electric field presents scattering. As the shape of power line in the electric fields is like semicircular arc or ellipse, there is some limits in the measurement depth of uniplanar scattering-field capacitive sensor, and its penetration depth is equal to 2/3 of center distance of adjacent driving and irritable electrode pole.
