ECE 594I Syllabus: Fall 2009 • Background for THz Field and Radiative Phenomenology: blackbody radiation, Kirchoff’s relation, and propagation through common materials (vapor, solids, and liquids) at THz frequencies • Electromagnetics and Propagation Effects: skin-effect losses, diffraction effects, surface roughness effects; waveguides, transmission lines, antenna types, etc. • Coherent Sources: multiplication up from RF region and difference-frequency generation (photomixing) from optical lasers; transistor amplifiers, FET- and HBT-based; vacuum-based devices. • Passive Detection and Sensor Principles: direct and coherent detection with and without pre-

Unformatted text preview: amplification, sources of noise, radiometry, system sensitivity metrics (e.g. NEP and NETD), system resolution metrics (spatial and spectral). • Active Detection and Sensor Principles: transmitter types and associated waveform, detection mechanism (direct, coherent and in-between), effect of noise, radar-range equation, statistical detection theory based on maximum-likelihood criteria; probabilities of detection, false-alarm, etc.; receiver-operating characteristics (ROCs) • THz Systems and Applications: radio astronomy, molecular spectroscopy (gas, liquid, and solid states), imaging of concealed objects, imaging of biological materials. 1...
