Sentence examples for radio frequency field from inspiring English sources

Here, we outline some of the theoretical and technical advances underlying this technique, particularly in terms of measuring and correcting for transmit and receive radio frequency field inhomogeneities.

Selective population inversion can be achieved rather independently of spatial radio frequency field inhomogeneities and with significantly reduced peak RF amplitude in comparison with the well-known sech/tanh adiabatic pulse.

This electrosmog is the result of the radio frequency field that our telecommunication infrastructure uses so we can all talk (virtually or otherwise) and text with one another.
