Lumped-capacitance method applied to measurements of complex dielectric permittivity in polar liquids from 100 MHz to 3 GHz Observations are made of standing-wave ratios in a slotted line terminated by the test cell. The final solution of the impedance equation with respect to epsilon ' and epsilo...
Lecture 6 Transit System: For Bi > 0.1 , temperature gradients within the medium are no longer negligible. Use of the lumped capacitance method would yield incorrect results, so alternative approaches must be utilized. TRANSIENT HEAT CONDUCTION WITH SPATIAL EFFECTS: LARGE PLANE WALLS, LONG CYLINDERS...
