20p. 2-You want to design an experiment for researching the behavior of electromagnetic field at the frequency of 8 kHz in a flog medium (can be modeled as a vitreous humor medium) however nowadays you don't know the other antenna properties, to see the EM effects at frequency 8 GHz design an experiment in the vitreous humor. Find a suitable medium instead of a vitreous humor medium in terms of electrical parameters. 20p. 3-You want to protect an ideal dipole antenna from outside condition without changing impedance matching of the antenna. For this purpose you want to use the shielding at distance 0.1 1 from the antenna. Determine the electrical parameters of the shielding. Explain will there be any change in the electrical parameters of the shielding at different frequencies.
