Abstract: In a Multiple Input Multiple Output (MIMO) system, an apparatus and method includes a Tightly Coupled Array antennas (TCA) or Current Sheet Antennas (CSA). Far-field radiation patterns from any current sheet antenna are formed from the combination of the fields generated by a set of currents on the CSA of array port orthogonal modes, such as the Characteristic Modes (CM). The CM currents are generated by excitation of the CSA element ports with corresponding orthogonal voltages or currents (eigenvectors). Since the radiation patterns of the characteristic modes are orthogonal and uncorrelated, multiple signals may be propagated along the radiation patterns of the characteristic modes, each signal using a different characteristic mode or a different set of characteristic modes. Therefore, a CSA antenna utilizing array port orthogonal modes such as array port characteristic modes can support MIMO communications despite the strong mutual coupling among the antenna elements.

Abstract: One embodiment provides an eviction system for dynamically-sized caching comprising a non-blocking data structure for maintaining one or more data nodes. Each data node corresponds to a data item in a cache. Each data node comprises information relating to a corresponding data item. The eviction system further comprises an eviction module configured for removing a data node from the data structure, and determining whether the data node is a candidate for eviction based on information included in the data node. If the data node is not a candidate for eviction, the eviction module inserts the data node back into the data structure; otherwise the eviction module evicts the data node and a corresponding data item from the system and the cache, respectively. Data nodes of the data structure circulate through the eviction module until a candidate for eviction is determined.
