# Magnetotelluric: Forward Modelling for 1 to 3 layers¶

Here you can visualize Magnetotelluric (MT) response of a layered earth, up to 3 layers in this interactive notebook.

• fmin: smallest measured frequency (Hz)
• fmax: highest measured frequency (Hz)
• nbdata: number of data points evenly spaced between fmin and fmax
• h (i): thickness of the layer i. Put it to zero to remove one layer
• $\rho_i$: electrical resistivity of the layer i, in ohm-m
• $\varepsilon_i$: relative dielectric permittivity $\varepsilon_r$ of the layer i
• $\mu_i$: relative magnetic permittivity $\mu_r$ of the layer i
• Plot Envelope fields: If activated (might be slow), plot the envelope of the E and H field for a given frequency (see fenvelope)
• F: plot the envelope for of the waves at 'F' Hz
