Abstract
The present invention relates to a method and apparatus for obtaining measurements of induced resistivity of objects from spaces such as within a down-hole hydrocarbon production well. The invention also relates to measuring the location or direction of objects based upon measured responses from objects engaged or impinges by one or more transmitted signals having different phase and directional orientation. The invention relates to generating at least one signal or wave and transmitting it through a plurality of different materials that may have varying properties of density, magnetic permeability and dielectric that may each emit a separate signal with altered phase and directional orientation. When used with electromagnetic signals, the resistivity of an object or media can provide useful information regarding the composition and the location of object or media. Such embodiments of the present invention utilize the principles of Magnetic Antenna.TM. and Magnetic Lensing.TM. to obtain information regarding the location and properties of the target object.
