I have obtained this picture from another website, but it explains the same thing as Don Smith. The higher the frequency, the less electrons travels in the wire. In HF electrons travels AROUND the wire. So no Ohm's law applies.
Ohm's law can apply on high frequency if the system is not in resonance.
High frequency + Resonance = Zero impedance = No ohmic losses.
