Sounds interesting but it should be treated with care without a more full description. There are 'one way' EN devices in RF Engineering (Circulators and Isolators) which force EM waves to 'go one way' but they involve dissipative elements and non-linearity.
When I read "defying the Law", I always wonder . . . .
