Problem 2 A 30 MHz uniform plane wave is propagating in the +z-direction in a medium filling the half-space z 2 0. The medium has conductivity 9 x 10-3 S/m, relative permittivity 4, and relative permeability 1. The reference direction for the electric field intensity is +x. The maximum value of the electric field intensity for z 20 occurs at t = 0 and z = 0 and is 200 [V/m]. Q2.6: At t = 0, what is the smallest distance z > 0 at which the magnetic field is zero? Answer in [m].

Problem 2 A 30 MHz uniform plane wave is propagating in the +z-direction in a medium filling the
half-space z 2 0. The medium has conductivity 9 x 10-3 S/m, relative permittivity 4, and relative
permeability 1. The reference direction for the electric field intensity is +x. The maximum value of
the electric field intensity for z 2 0 occurs at t = 0 and z = 0 and is 200 [V/m].
Q2.6: At t = 0, what is the smallest distance z >0 at which the magnetic field is zero? Answer in
