As can be seen in Figure 2, ripple in half-wave CWVM is periodic with almost symmetrical shape relative to horizontal line; that is, peak and valley are almost equal with 180[degrees] phase difference.
Therefore, the quantum case n=3, the length of the quantized experienced [[lambda].sub.enz]/2 half-wave of de Broglie in TS wires will be numerically [[lambda].sub.enz]/2 [approximately equal to] [DELTA][z.sub.nci] + [delta][z.sub.nh] [approximately equal to] 107 mm.
For example, a possible solution for obtaining smooth sine half-wave current of EVA (excluding high-frequency ripple) using a resonant half-bridge switching power converter is given in detail into reference [20].
For each buckling half-wave number i, there is a corresponding critical buckling load [([F.sub.x]).sub.cr].
The total thickness of the RBSN Ceralloy 147-010F slab is taken as 7.13 mm, which is the optimized half-wave wall thickness at 10 GHz (antenna operating frequency) corresponding to maximum power transmission for TE polarization (or perpendicular polarization) at high incidence angle 65[degrees] for the streamlined radome considered in this work.
The purpose of the paper is to develop an optical scheme for identifying the correspondence between the investigated crystal plate and the quarter-wave (half-wave) plate, according to the intensity of the transmitted radiation.
For each pair of half-wave numbers (tn, n) a certain number of circular frequencies are obtained depending on the order N chosen for the exponential matrices [A.sup.**.sub.j] and the M number of fictitious layers.
In general, when half-wave dipole antenna is assumed, topology with dipole antenna is more complex than isotropic case.
The ([n.sub.e] - [n.sub.o]) of the half-wave plate used in this paper is 180[degrees].
Aiming at few features that are available in arc suppression coil to ground system, single fault line selection method is not very reliable, and this paper regards the ratios of the first half-wave extremes between neighboring lines and spectral kurtosis (SK) relative energy entropy as features to select the fault line, a stepped fault line selection method is proposed by utilizing two kinds of features.
Since the wire antenna is similar to a half-wave dipole and the cable in a typical setup usually much longer than the board size, the effective length of the wire antenna can be approximated as the cable length, [l.sub.cable].
