In thermotropic smectic-A liquid crystals, the strong energetic preference for constant layer spacing often results in the spontaneous formation of focal conic domains (FCDs) to resolve large distortions. Collections of many FCDs self-organize into arrangements such as 2D lattices and polygonal textures, whose packing geometries involve beautiful geometric matching rules to ensure that smectic layers remain smooth. However, strong confinement can frustrate the typical FCD self-organization principles. I will discuss three such scenarios:
