Next, a popup box for content relevant to the click-to-dial icon and a click feature on the popup box are created to retrieve call destination attributes for viewing by a user. The refractive index of KTN can be reduced considerably, and this controlability widens the degree of freedom in the design of optical waveguide devices. The reinforcement is useful to shore up damaged structures or to provide, for example, additional protection against natural phenomena such as earthquakes or storms.
