Pulse bursts of microwave energy were used to stimulate resonant-type acoustical response in a rectangular muscle-equivalent model and in a spherical brain-equivalent model. The rectangular model was irradiated using a military radar transmitter at 5.655 GHz, 200 kW peak, and the spherical model was irradiated using a pulse-type cavity oscillator at 1.10 GHz, 4 kW peak. Hydrophone transducers were implanted in the models to record the microwave-induced mechanical vibrations. Four properly timed radar pulses produced a threefold increase in the acoustical amplitudes in the muscle model. In the spherical model, a pulse train of three properly timed microwave pulses doubled the stress wave amplitudes as recorded by the implanted hydrophone. These results show that certain pulse parameters of microwave irradiation can be adjusted to increase the intensity of induced mechanical vibrations in both rectangular and spherical tissue equivalent models.
利用微波能量脉冲来刺激矩形肌肉等效模型和球形脑等效模型中的共振型声学响应。矩形模型使用峰值功率为200千瓦、频率为5.655吉赫兹的军用雷达发射器进行照射，球形模型使用峰值功率为4千瓦、频率为1.10吉赫兹的脉冲型腔振荡器进行照射。将水听器换能器植入模型中以记录微波诱发的机械振动。四个定时恰当的雷达脉冲使肌肉模型中的声学振幅增加了两倍。在球形模型中，一串三个定时恰当的微波脉冲使植入的水听器记录到的应力波振幅增加了一倍。这些结果表明，可以调整微波照射的某些脉冲参数，以增加矩形和球形组织等效模型中诱发的机械振动强度。
