Investigation of Wang's model for room-temperature conduction losses in normal metals at terahertz frequencies

This paper investigates Wang's application of Harrison's screening potential theory, which is used for the modeling of room-temperature conduction losses in normal metals at terahertz frequencies. The methodology formulated for this theoretical model is examined in detail. Fundamental equations are derived from first principles and used as reference in this investigation. A summary of the derivations and the results from this work are reported for the first time. From this detailed investigation, it has been found that there are serious discrepancies with Wang's general methodology. As a result, it appears that it may be inappropriate to use Wang's model to describe the intrinsic frequency-dispersive nature of normal metals at room temperature. The findings from this work add weight to the view that there is neither theoretical nor experimental evidence to support the existence of anomalous behavior in normal metals at room temperature.
