In this chapter, concerns with the ranges below and above UV, characterized by ionization-that is, the frequency is sufficiently high to ionize molecules based on Planck's equation. The frequencies are so high (above 750 THz) that many forms of radiation can penetrate through materials, and therefore the methods of sensing must rely on different principles than at lower frequencies. On the other hand, below the IR region the electromagnetic radiation can be generated and detected by simple antennas. Thus we will also discuss the idea of an antenna and its use as a sensor and an actuator.
