Conceal an entrance by means of superscatterer
Abstract
Based on the fact that superscatterer can look like a scatterer bigger than its geometric size, we propose a design of hidden portal in which an entrance is concealed from the electromagnetic wave detection. Such a superscatterer is realized by coating a negative index material shell on a perfect electrical conductor rectangle cylinder. The results are numerically confirmed by full-wave simulations both in the far field and near field.
