Code to produce v1

This code takes the input of the Y1 matrix and the initial impedance to produce a vector of v1 values, using equations discovered in previous research. This code also produces v2 as well as yin which is not needed for our purposes.

%function to produce values for v1 given a Y1 and S0 function v1 = nfc(Y1,S0)n = 41; Z0 = 50;A = S0; S = zeros(n,n);for k = 1:n, for l = 1:n,S(k,l)=A(k,2*l-1)*cos(A(k,2*l)*pi/180)+i*A(k,2*l-1)*sin(A(k,2*l)*pi/180); endend Zparam = Z0*inv(eye(n)-S)*(eye(n)+S); % Zparameters of n-port systemYparam = inv(Zparam); W = Yparam; % Ys matrixm = 20; % Number of receivers r = n-1; % Maximum n-1W11 = W(1:m,1:m); W12 = W(1:m,(m+1):r);W13 = W(1:m,r+1); W21 = W((m+1):r,1:m);W22 = W((m+1):r,(m+1):r); W23 = W((m+1):r,r+1);W31 = W(r+1,1:m); W32 = W(r+1,(m+1):r);W33 = W(r+1,r+1); Yc = inv(W22 - W21*inv(W11)*W12 + Y1); % Complex Y matrixY = real(Yc); % Matrix M in paper YY = imag(Yc); % Matrix N in paperP = W22-W21*inv(W11)*W12; %*****W11+Y1 changed to W11 P1 = W31*inv(W11)*W12-W32; %*****W11+Y1 changed to W11M = real(P); M = 0.5*(M+M');v2 = P1*(Y+YY*i); % Voltages as input to Y1 v1 = -v2*W21*inv(W11)-W31*inv(W11); % Voltages not connected to Y1 %*****W11+Y1 changed to W11yin = v1*W13+v2*W23+W33; return

Using this code, we could feed the function a variety of Y1 values to try and determine a pattern between the Y1 and the v1. This way, we were able to modify Y1 in whichever fashion we liked to see if there were visible patterns that could be seen within the v1 values. The code that calls this function then uses the value of v1 and Y1 to plot graphs and look at specific values.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.

anybody can imagine what will be happen after 100 years from now in nano tech world
Prasenjit
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
