Possible ways of generating plasmas with sufficiently high electron density and gas pressure for efficient absorption of radar waves are studied by means of numerical solution of fluid equations and analytical estimates, using available coefficients on ionization and recombination. It is found that helium, or a helium-argon mixture is the most suitable gas. The computational modeling in two dimensions indicates that stable discharges can be generated with dielectric-coated electrodes at driving frequencies in the range of 1 MHz. One-dimensional computations were undertaken and reached densities in the vicinity of the required values. One problem is the rather high power consumption that is expected for a sufficiently dense plasma. Both the numerical simulations and theoretical estimates indicate that the required power consumption is in the range of several tens of kW/m2. In order to obtain more conclusive results, an experimental test would be necessary. The study was carried out at the Department of Electrical Power Engineering and Department of Electromagnetics at Chalmers, from October 2001 until March 2002, and was supported by FMV and FOI.
