Abstract

The paper presents the brief notes on some questionable points of modern magnetotellurics. These controversial points are: (1) nature and structure of the magnetotelluric impedance tensor, (2) magnetotelluric dispersion relations, (3) the magnetotelluric eigenstate problem, (4) separation of local and regional effects (the local-regional decomposition), (5) sensitivity of the TM and TE modes of the two-dimensional field, (6) robustness of the TM and TE modes, (7) identification and correction of the static shift, and (8) strategy of the two-dimensional interpretation: unimodal or bimodal inversion? Consideration of all these topics gives a better insight into problems and potentialities of magnetotellurics.
