Controlling Directionality and Dimensionality of Radiation by Perturbing Separable Bound States in the Continuum

A bound state in the continuum (BIC) is an unusual localized state that is embedded in a continuum of extended states. Here, we present the general condition for BICs to arise from wave equation separability. Then we show that by exploiting perturbations of certain symmetry such BICs can be turned i...
