Abstract
One embodiment provides a line of sight detector. The line of sight detector includes a first TeraFET (field effect transistor) including a first source, a first drain, a first gate, and a first channel having a first end and a second end. The line of sight detector further includes a first source antenna coupled to the first source; a first drain antenna coupled to the first drain; and a third antenna. Each antenna is configured to receive an incident radiation signal having a frequency in a sub terahertz or a terahertz frequency range. Each antenna is positioned a respective distance from each other antenna. Each distance is less than one wavelength of the incident radiation signal.
