How to 3D plot a circle with radius of 1 in x y and sine wave in z?

I want to 3D plot a circle looks like the image below. (Sorry for the poor drawing) The figure is a circle of radius 1 in xy surface and the circle should have a sine wave in z-direction. It's exactly same shape with pringles chip.

%Position of center of chip in 3D space
x0 = 1;
y0 = 1;
z0 = 1;
r = 1;%Radius of chip
d_theta = 2*pi/60; %Differential Angle
th = 0:d_theta:2*pi; %Angle Vector
height = 0.5; %Height of wave in the chip
% Create the x, y, and z positions
x = x0+r*cos(th);
y = y0+r*sin(th);
z = z0+height*sin(2*th);
