In this talk, we report on the phase-randomizing functionality of a new absorber (microcoil absorber) consisting of metal-plated microcoils of spiral alga Spirulina dispersed in a low-reflective-index material. We fabricated a sample of the microcoils dispersed in a styrene foam and measured the time-domain waveform of the normal reflection by terahertz time-domain spectroscopy. Then, it was confirmed that the reflected waveform consisted of many small pulses and that the phase of the reflected waveform was randomized.
