Direct_sequence_spread_spectrum
Assume that a direct sequence spread spectrum system uses the Barker code of length 7 (N=7) as its spreading sequence.
a. Randomly generate 8 symbols (d0~d7) from the set {+1,-1}.
b. If each chip of the Barker code is denoted as cj, j=0~6, spread each symbol di by the Barker code. (Please refer to p. 17 of the slides.) Use “stem” to plot the signals before
spreading and after spreading

SharifPWE_BZplot
The ouput is the TE/TM band structure (first five bands) along pricipal
directions (G-X-M-G) of a square-lattice photonic crystal with unit cell
consisting of a substrate of "epb" relative permittivity with circular
rods(holes) of "epa" relative permittivity and radius "r".
Usage is
SharifPWE_BZplot(N,RES,r,epa,epb)
N: N in PWE algorithm (number at which the summations are truncated)
RES: number of the divisions on every side of BZ#1
r: normalized radius of the circle of holes/rods (0<r<0.5)
epa: relative permittivity of holes/rods
epb: relative permittivity of the substrate

all-time-apprent-resistivity
将接地长导线源沿导线方向分解成多个电偶极子源，对若干电偶极子源产生的响应进行叠加得到接地长导线源的Hz响应。计算结果表明接地长导线源的Hz响应与电阻率之间的关系也为单值关系。(Decompose the grounded long wire source along the wire direction with several electric dipole, and overlay the response which produced by the electric dipole as the grounded long wire source’s response. The result show that the relationship between the Hz component of ground long wire source and resistivity are also single valued.)
