Abstract
In an interaction between slow electromagnetic waves carried by metallic circuits and drifting carriers in solids it is shown that the presence of negative differential mobility inhibits the traveling‐wave tube type of interaction at electron drift velocities greater than the phase velocity. At electron drift velocities below the wave phase velocity, however, the presence of negative differential mobility provides gain. The result agrees with the physical picture of an ``absorption'' by a negative resistance giving wave growth.Keywords
