From (2.1.36) and (2.1.34), the k'th terminal current follows as N aqk dv 1 m aqk dx 1 ik = a + . d , (2.1.37)1 avj dt j=1 ax dt k=1,2,. .., N. If we specify that our multivariable system is electrically linear (a situation that occurs when polarization P is a linear function of electric field intensity) we can write the function of (2.1.36) in the form N qk CkJx 1 , 2, ..... XM)Vf, (2.1.38) $=1 k=1, 2,. .. N. Equations 2.1.36 and 2.1.38 can be inverted to express the voltages as functions of the charges and displacements. This process was illustrated for magnetic field systems by (2.1.19) through (2.1.24). 2.1.2 APDF Split DEMO : Purchase from www.APDF.com to remove the watermark...
