If light could bend around a person ,would that make the person invisible?

Question

If we place an object such as a coin in front of the light source ,e.g a candle we cant see the candle through the coin but if the size of the coin would be comparable to the wavelength of visible light the we can see the candle through the coin because light would bend around it ... So my question is  , can a device like this be designed

a device that generates electromagnetic waves whose wavelength initially is in the visible region then whose wavelength continuously increases then bends around the person then its wavelength sort of decreases till it reaches the eye of the receiver as visible light .So the person would be invisible to the reciever. Is such a device possible? Is my idea stupid? And if at all we are able to make such a device would it happen just like i said or is my idea just wrong?

Well, light can only travel in straight linear paths, so that machine would be implausible and also it can't be plausible because light would have to travel around the person (it wouldn't work as your drawing suggested because the light would have to change its frequency to become a higher wave) and because it can only travel in a straight line (as I said) not plausible!

However this is a great mind experiment.
If we could somehow create circular (going in a circe) light then it would be possible.  
BUT if any other light is present then I don't know if it could work.
