The effects of metamaterial on electromagnetic fields absorption characteristics of human eye tissues.
Gasmelseed A, Yunus J. · 2013
View Original AbstractComputer modeling shows metamaterials didn't reduce electromagnetic absorption in eye tissues at cell phone frequencies, questioning some shielding claims.
Plain English Summary
Researchers used computer modeling to study how electromagnetic fields from a 900 MHz antenna (similar to cell phone frequencies) are absorbed by different parts of the human eye when a special material called metamaterial is present. They found that the specific absorption rate (SAR) - a measure of how much electromagnetic energy the eye tissues absorb - remained unchanged regardless of the metamaterial's properties. This suggests that certain engineered materials may not provide the electromagnetic shielding benefits for eye protection that some might expect.
Study Details
The interaction of a dipole antenna with a human eye model in the presence of a metamaterial is investigated in this paper.
