I am building a project where an object will be fitted with an RF transceiver and where it will face wooden walls as obstacles, with constant thickness "t". I am trying to look for an equation that would give the appropriate radio frequency that I would need to generate to have a radio wave either:
A. Reflect at the 1st wooden wall directly in front of the object and then be received directly by the object.
B. Pass through x number of wooden walls in front of the object that is transmitting the wave and reflect at the x+1 wall, where the reflected wave would pass back through the same x number of wooden walls and be received at the object.
For example:
-Have the wave reflect at the first wall and reflect back directly to the object's receiver.
-Have the wave pass through the 1st wall, reflect at the 2nd wall, and then pass through the 1st wall to be received back at the object's receiver.
-Have the wave pass through the 1st and 2nd wall, reflect at the 3rd wall, and then pass through the 1st and 2nd wall to be received back at the object's receiver.
And so on..
In each of these cases, I would probably need to generate a specific radio frequency. The question is what would be the equation/theory in order to determine each of these frequencies? I also would assume that wood has an attenuation constant that I would have to account for.
