The electrical characteristics that make up

characteristic impedance.

Having derived all the primary parameters of the 3-phase power cable (Table I) its

characteristic impedance and propagation constant were able to be obtained.

The

characteristic impedance at each section of the proposed transition is kept at 50 [OMEGA] to have a wide bandwidth.

The theoretical transmission lines

characteristic impedance is 638 D (C [approximately equal to] 5pF/m, L [approximately equal to] 213 1nH/m, [beta]/[omega] [approximately equal to] 3.4e-9) .

One of them calculates the strip width of the coplanar waveguide and the other calculates the sloth width of the coplanar waveguide having a desired

characteristic impedance for a given dielectric substrate material.

where [Z.sub.910] is the

characteristic impedance of TL9 and TL10 and [f.sub.4m-2] is the (4m - 2)th harmonic.

* The terminal branch impedance influences the position of peak and notches and the attenuation of notches significantly decrease with impedance larger or lower than

characteristic impedance of power line.

Specifically, this factor uses the ratio of

characteristic impedances for a non-complementary CPS ([W.sub.CPS] [not equal to] [S.sub.CPS]) to the

characteristic impedance of self-complementary CPS ([W.sub.CPS] = [S.sub.CPS]), where [W.sub.CPS] is the metal width, [S.sub.CPS] is the strip spacing, and the impedance of CPS is given by [36].

The attenuation could also be reduced by a thicker line metallization or by increasing the line width and so decreasing the

characteristic impedance.

This paper proposes a novel modified CRLH structure that has a continuous

characteristic impedance distribution inside the passband, and sharp skirt characteristics in the upper or lower stopband whether the CRLH unit cell is right- or left-handed.

parameters are enhanced and become frequency dependent, we can expect that the

characteristic impedance is also frequency-dependent.

Their topics include the analysis of nonhomogeneous helical systems using electrodynamical methods, calculating

characteristic impedance of multiconductor lines, investigating slow-wave systems with versatile electromagnetic simulation and design tools, applying slow-wave structures to deflect electron beams, and the computer-aided design of electrodynamical delay lines.
