    18481849<p>To provide easy access to the orientation of the core-shell cylinder, we define the axis of the cylinder using two angles &theta; and <span style="font-family: 'Arial','sans-serif';">&phi;</span>. Similarly to the case of the cylinder, those angles are defined on Figure 2 in Cylinder Model.</p>
