我们提出了一种新型的共振质量引力波探测器，截顶二十面体引力波天线。它将是全向的，并且能够测量检测到的波的方向和极化。我们求解了该系统的模型，计算了其应变噪声谱，并得出结论：在相同的噪声温度下，其角平均能量灵敏度将比等效杆式天线高56倍
We propose a new type of resonant-mass gravitational wave detector, a truncated icosahedral gravitational wave antenna. It will be omnidirectional, and able to measure the direction and polarization of a detected wave. We solve a model for this system, calculate the strain noise spectrum, and conclude that its angle-averaged energy sensitivity will be 56 times better than the equivalent bar-type antenna with the same noise temperature
