Abstract: The Breakthrough Starshot project proposes using radiation-pressure propulsion to send multiple spacecraft in the gram-range mass to interstellar targets. There are numerous engineering challenges to accomplishing this mission, but their project discusses speeds and accelerations previously only discussed for cannon projectiles and particle physics experiments. This article examines the problem from first principles to see if the project is even orders-of-magnitude possible. A preliminary check on their numbers seems to confirm that the project is possible in principle.

Instead of
"The CDTA is not free from parasitic input capacitances and it can operate in a wide frequency range due to current-mode operation."
something like "the CDTA is less sensitive to  parasitic input capacitances..."
is more appropriate.
