The ionosphere is an ionized layer that extends
between 50 km and 1000 km altitudes in the atmosphere. It plays an important
role in atmospheric electricity. The ionosphere has the number of electrically
charged particles and thus, it affects the propagation of the radio waves. In
this study, magnitudes of impedance for different seasons and different
geomagnetic activity periods in the ionospheric plasma are calculated using the
real geometry of Earth. It is observed that the impedance of the ionospheric
plasma in all directions generally has high values for all seasons. The
diagonal components of the tensor of the impedance are greater than the other
components. It is also observed that the ionospheric plasma, generally, has
weak conductivity in all directions and seasons. Impedance varies inversely
with electron density. Hence, geomagnetic activity periods which lead to an
increase in electron density decreases the impedance. It is observed that the
ionospheric plasma has a reactive character in the geographic coordinates where
the study was performed. The ionosphere displays a dielectric structure.
