range was set between 4000-625 cm-1 having 256 scan cycles and a resolution of 8 cm-1.
The spectral FDTD (SFDTD) method is a novel technique in which the constant transverse wave-number (CTW) wave is applied .
The application, the SFDTD, is mainly using a constant transverse wave-number (CTW) wave to directly implement the PBC in the time domain.
where k is the wave-number in the microwave lens region.
where [k.sub.0] = 2[pi]/[lambda] is the wave-number for free space, k = [k.sub.0]/[([epsilon].sub.r]).sup.1/2] is the dielectric wave-number, W is the length of the TL (Figure 1) connecting the array port n on the inner contour of the RF lens to the corresponding array element n on the outer contour, and d is the uniform spacing between adjacent microwave antenna array elements.
Recently, another new formulation, named spectral FDTD (SFDTD) was proposed to deal with the problem [27,28], because the constant wave-number (CTW) wave is used, there is no delay in the transverse plane and the PBC can be implemented directly in the time domain.
The incident wave is considered as a constant transverse wave-number wave in our discussion, the field components can be seen in Fig.
In our work, the incident wave is considered as a constant transverse wave-number wave, presented in Eq.
The CTW wave is introduced into the computational domain, with the transverse wave-number [k.sub.x] ranges from 20 [m.sup.-1] to 800 [m.sup.-1].
where [k.sub.x], [k.sub.y] represent transverse wave-numbers, which are assumed to be constant numbers (independent of frequency).
1 modes appear to be more important in the stratospheric variability during warm than for cold-ENSO winters (i.e., 31% against 21%, respectively).
