Varying the Constituents of Meta-materials to Improve Efficiency
Earthquakes are catastrophic geological disasters that are a major cause of destruction and death. It reduced the number of lives and caused countless amounts of property damage. If the effects of earthquakes could be lessened, it would save innumerous lives and money. • On average, about 63,000 lives are lost per year (USGS, 2012) • The purpose of this project is to test different materials to determine its effects on the meta-material’s efficiency. Problem & Purpose
Meta-materials are materials engineered to have optical, thermal, or other specific properties that naturally occurring substances do not. These materials can block, bend, and manipulate all sorts of waves. • Meta-materials were first discovered in 1986 by a Russian theorist, Victor Veselago. • Meta-materials work mostly because of their shape. The material used to make meta-materials does not have a huge impact on the functionality of the meta-material itself. The only conditions are that it must be made of two or more different materials that are also different from what it is surrounded by. Background
The research hypothesis for this project states that if different materials are used to construct meta-materials, then it will have a significant effect on the meta-material’s efficiency. Hypothesis
Title: Varying the Constituents of Meta-materials to Improve EfficiencyHypothesis: If different materials are used to construct meta-materials, then it will have a significant effect on the meta-materials’ efficiency.IV: Different constituent of Meta-materials; Frequency DV: Acceleration (m/s/s)Constant: Loud Speaker, 1-Axis Accelerometer, Vernier Lab Quest, Frequency, 17.1 kg of dirt, 37x24x28cm box, Model Building, Position of meta-materials Experimental Design Diagram

Figure 5: This graph shows the standard deviation of the acceleration for each material. Results
Figure 6. This graph shows the percentage difference of the average acceleration between the three materials per frequency. Results
Research hypothesis accepted. • Data of experimentation of one material’s meta-material was significantly different from the data of another • The null hypothesis was rejected. The research goal was achieved. Discussion & Conclusion
