Ok, i'm from the old school electronics where you had to deal with individual components, not so much the micro chip stuff and troubleshoot down to a component, so when I have friends whom have questions like why their inductive charger isn't working and I find them setting it on top of a metal desk, I can explain to i'm blue in the face, but what they are really looking for is an answer to the problem.
I knew the equations but never really had to deal with capacitive or inductive tuning / coupling circuits. So, in knowing how conductors are used to 'steer' radio waves or dampen them, even to use a faraday cage as an example, I was hoping someone knew what could stop the dampening effect of the metal desktop or even redirect the inductive field upward. I haven't dealt with inductive charging pads, therefore I"m not sure if they are assigned a certain frequency in the bandwidth spectrum. I saw one that said it operated at 1.67 Mhz but I don't know if this is a stardard. IF product developers shared the exact frequency I'd imagine it would be as easy as finding the wave length but no such information was given. Any ideas past good ole trial and error based on best guestimation ?
