This "mutual capacitance
" can be responsible for the transfer of energy from one trace onto other nearby traces; i.e., coupling.
Table III shows the finite element results for the self and mutual capacitance
per unit length of shielded symmetrical coupled microstrip lines with different dielectric constants, 3.2, 4.3, and 6.8.

where [C.sub.t-c] represents the effective mutual capacitance
between the trace and the attached cable and [C.sub.in] the input capacitance of the wire antenna model.
While mutual capacitance
touch sensing measures capacitance between two electrodes, self capacitance touch sensing measures capacitance of single electrode to ground, utilizing the field generated from the user to induce minute changes within the sensors field.
The notions of self and mutual electric conductance and the self and the mutual capacitance
are formulated for the magnetic contours.
It also increases the mutual inductance and mutual capacitance
. Crosstalk can be traced to mutual inductances and capacitances between traces, so they must remain low.
Cvp and Cvn are respectively capacitance of vias on the non-inverting and inverting lines, and Cm represents mutual capacitance
. Here only capacitance is considered, although a more complete via model also includes inductance.
Capsi and Adelman provide expressions in terms of self and mutual capacitance
. It is more convenient to design the filter using the concept of even- and odd-mode impedances rather than self and mutual capacitance
per unit length.
