摘　　要：提出了一种实验室尺度上电磁引力辐射的新模型。理论分析表明，在体积相同的情况下，复合介质电磁谐振腔在其最优方向的引力辐射能流密度比单一介质谐振腔高出４个数量级，为了获得可供探测的引力辐射能流密度，Ｇｒｉｓｈｃｈｕｋ和Ｓａｚｈｉｎ曾提出尺寸为１０ｍ×１０ｍ×１０ｍ的巨型单一介质电磁谐振腔模型。计算表明，采用复合介质电磁谐振腔，可将其尺寸减小到１ｍ×１ｍ×１ｍ。这对于谐振腔的低温操作将极为有利。new modd for electromagnetic gravitational wave radiation in the laboratory scale isproposed.A theoretical analysis shows that the energy-flux density of the gravitational waveradiation of an EM resonator with a complex medium in the optimal direction will be 4 ordersof magnitude higher than that with a single medium resonator if the volumes are the same.In order to produce a detectable energy-flux density,a giant single medium EM resonatorwith a dimension of 10 m×10 m×10 m was proposed by Grishchuk and Shazhin.Calculationby the authors shows that this dimension could be reduced to 1m×1m×1m should a com-plex medium EM resonator be used.
