With increasing sensitivities of the current ground-based gravitational-wave (GW) detectors, the prospects of detecting a lensed GW signal will be high in the coming years. In addition to strong lensing where ray optics approximation holds well, a GW signal may also undergo microlensing, where wave effects dominate. When a GW signal is intervened by a compact object or a population of them, it leads to interference patterns in the signal that may affect its morphology. In this talk, we will look at a broad overview of the effect of microlensing on gravitational waves: its impact on the detection and inferred parameters of GW signals; can the non-inclusion of this physical effect in the waveform model affect tests of gravity?; Can eccentric signals mimic microlensing?; What to expect in case of microlenses embedded in macrolens?
