alpha2cen Posted January 26, 2011 Share Posted January 26, 2011 Does alternating current emit electromagnetic wave? If so, how about collating the disposable energy by using antenna? Link to comment Share on other sites More sharing options...
swansont Posted January 26, 2011 Share Posted January 26, 2011 It does, if it's from a single conductor, but there are ways to combat it. Coaxial cables, or paired cables, give no far-field emission. Coax gives you a Faraday cage, and pairing the line with the return gives destructive interference. Link to comment Share on other sites More sharing options...
