Figure 1

(A) The absolute value of the E-field at 90 GHz with the longitudinal planar sensor output, 20 ps orthogonal pulse. (B) Planar sensor at 20 mm within the canal showing the increased signal in the central region. (C) Longitudinal planar sensor at 145 ps with significant reflection from the surface of the tympanic membrane. (D) Time domain variation of the absolute value of the E-field, point sensor 20 mm into the canal. (E) Planar sensor placed on the surface of the tympanic membrane (maximal intensity). (F) Planar sensor at 0.03 mm in the tympanic membrane. The central region of the tympanic membrane receives the bulk of the incident radiation. (G) 100 ps orthogonal pulse sensor output at 205 ps into the simulation showing attenuation of the signal near the edges. (H) Planar sensor output at 238 ps with reflection from the surface of the tympanic membrane causing destructive interference.
