Thus wood was cheaper than artificial material, and it showed.

Modern fibers that are made from older artificial materials include:

Pads are available in either natural or artificial (synthetic) materials.

However, these artificial materials are able to create the overall effect of negative refractive index.

"I see a great many artificial materials being used here," she said.

Most of the trees are made of artificial materials and available in all sizes.

Researchers are examining ways to reproduce this capability with artificial materials.
