Figure 3 Temporal evolution (a) vacuum and (b) Tellegen medium, magnitude vs. spatial position) of the electric field E x in three different spatial positions (5010, 5110, and 5210). The time shift of the second minimum, between every case, is shown between electric and magnetic field is easily obtained from the simulation, and compared with the theoretical one (180 ° � arctg[�1 � � 2 /�] � 107.5°) [8], the error being less than 0.1%. The wave impedance (defined in this case as the relation between the amplitudes of E and H) is easily obtained, too, and compared with the theoretical value (1, if we use normalized units), being also coincident, with a relative error of less than 0.5%. Finally, the phase speed of the wave is computed observing the fields in different positions (5010, 5110, and 5210), and the time shift between them (Fig. 3). It agrees well with the normalized theoretical value v theor � 1/�1 � � 2 � 1.05 c, (c being the phase velocity in vacuum). The velocity obtained in our simulation is v Tellegen � 1.07 c. The relative error is, then, less than 2%
