| Abstract |
Open cell conductive foams (OCMF) have been recently suggested as an alternative to perforated metal patches for efficiently handling gas desorption from the beam pipe wall due to intense synchrotron radiation, yielding superior performance in terms of residual gas concentration and beam shielding. Experimental work is ongoing to assess their properties, including secondary emission yields and beam coupling impedances. In this communication we attempt a review of the Literature about electromagnetic modeling of OCMF, and outline a general framework for computing the surface impedance of OCMF walls and deriving the longitudinal and transverse beam coupling impedances thereof, based on effective medium theory and electromagnetic reciprocity. A critical analysis of the relevant modeling approximations is included.
