The math is VERY well known. There's are a couple of excellent technical 
papers about  this in one of the ARRL Antenna Compendiums.  Another 
place to see this is on the Times data sheets for their LMR cables. Look 
below the graph of loss vs frequency, where there is an equation for 
loss as a function of frequency. The first term is resistive loss and 
increases as the square root of frequency, the second is dielectric 
loss, and increases linearly with frequency.  Put the equation in a 
spreadsheet and plot the curve. The square root term is skin effect.
