Abstract. Possibilities to decrease the field intensity in semi-shadow zone of the field diffracted over the edge of half-plane are dicussed. For that purpose a semi-transparent edge is treated. Both qualitative Kirchhoff analysis and strict numerical optimization are performed. It is shown that semi-transparent edge with reactive impedance allow for significant shadowing improvement versus perfect conductive one. Results are applicable to electromagnetic compatibility, jamming protection and multipath error mitigation. 

Key words: Half-plane diffraction, semi-transparent sheet, semi-shadow zone.
