How to indicate the maximum value on the given curve
z1 = [0.00008 0.009]';
a11 = -1:0.001:1;
k1 = atan(((0.01/2 + a11)./z1)) + atan((0.01/2 - a11)./z1);
plot(a11,k1(1,:),'-k',a11,k1(2,:),'-r')

text(a11(idx_k1(1))+0.05,k1(1,idx_k1(1)),num2str(k1(1,idx_k1(1))))
text(a11(idx_k1(2))+0.05,k1(2,idx_k1(2)),num2str(k1(2,idx_k1(2))))

Another way to plot a marker at the maximum point, assuming you don't want any other markers, is to use the MarkerIndices property of the line.
x = 0:180;
s = sind(x);
[~, location] = max(s);
plot(x, s, 'o-', 'MarkerIndices', location, ...
'MarkerFaceColor', 'r') % Make the marker stand out in red
