DON'T MISS TOMORROW'S AOC VIRTUAL SERIES: Metamaterials 101
Thursday, July 28 | 14:00-15:00 EDT
A new world of materials is emerging called "metamaterials" where physical properties are altered to achieve results that don't naturally occur in nature. Metamaterials are materials that use resonance properties to "cheat" nature and cause effects to occur that may benefit antenna radiation and possibly support "cloaking" devices. "Metamaterials" simply means materials that are beyond normal material properties. Their unique properties are created when resonance conditions are created. Often this is accomplished by creating cavities along the material surface that resonate at the design frequency. Switchable metamaterials can be used to dramatically reduce radar cross section or to modulate beam patterns for surface mounted antennas.
This lecture on metamaterials will cover the basic physics of these materials and will demonstrate several practical applications.
