We analyze the transmission of highly charged ions (HCI) through microcapillaries. The interaction 
of an HCI with the internal surface of the capillary is treated within the framework of dielectric 
response. For projectiles transmitted through a Ni capillary calculations for the impact parameter, 
angular distribution, and charge states of hollow ions/atoms are presented. We find the charge state 
fractions of transmitted projectiles in good agreement with recent experiments.
