While it\u2019s often useful to have small and portable antennas, certain frequencies of radio broadcasts require antennas that are extremely large.\u0026nbsp;For instance, think of the size of AM radio towers and even cell phone towers, which are hundreds of feet high.\u003C\/p\u003E\u003Cp\u003EAt lower radio frequencies, this becomes an extremely difficult problem, as the size of the radio wave being broadcast is very big. But Cohen and his team would like to be able to generate low frequency radio waves better, because unlike cell phone signals, they propagate around the world.\u003C\/p\u003E\u003Cp\u003ECohen\u2019s proposed program aims to overcome this problem by building an antenna out of a plasma. A common example of a plasma is what is inside your fluorescent light bulb. It results when you put a high voltage across a gas, which rips apart the molecules. When that happens, a plasma can conduct electricity, much the way metal does (most antennas are built out of metal). But, unlike metal, the plasma can be turned off quickly, simply by shutting off the voltage.\u003C\/p\u003E\u003Cp\u003EUsing the ability to turn a plasma on and off very quickly, and doing it in just the right fashion, Cohen and his team can control the properties of the antenna quickly enough to boost the efficiency of a low frequency antenna, even when it is rather small.\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EECE Assistant Professor Morris B.
