Neighboring resistivity anisotropy determination

A method comprising:

• disposing a logging tool into a formation, wherein the logging tool comprises:
• an electromagnetic transmitter antenna;
• and
• an electromagnetic receiver antenna, wherein at least one of the electromagnetic transmitter antenna or the electromagnetic receiver antenna comprises an electric field antenna;
• transmitting a magnetic field signal into the formation from the electromagnetic transmitter antenna;
• receiving a reflected electric field signal or a magnetic field signal from the formation with the electromagnetic receiver antenna;
• measuring the reflected electric field signal or the magnetic field signal from the formation with the electromagnetic receiver antenna;
• and
• identifying one or more anisotropy properties of adjacent layers in the formation from the reflected electric field signal or the magnetic field signal, wherein the electric field antenna allows detection of the one or more anisotropy properties based on the reflected electric field signal, the magnetic field signal, or both.
