No papers that I know of Guy, just the word of a consulting engineer
who said he applied in the 60's and said it would not be considered as a
solution for even a slight pattern control to protect another station.
He finally had to go to a two tower array, another ground system, a
phaser, a day night switching control and a lot of bucks for the owner.
Station now are allowed lowering power to accomplish protection but back
then it was 250w, 500w, or 1KW, etc. Nothing in between for a single
tower set up. Now they permit single tower daytimers to operate at
night with very low power levels as low as a few watts to keep their
station on at night. I am sort of certain that some ham has modeled the
pros and cons of a slant wire feed for a grounded tower but I have never
seen such results published. Some hams tell me they do this to bring the
feed wire into the shack so they can use the tuner there to get a decent
match across the band.
