The differentiated service-based graceful degradation layer (DSGDL) allows cloud-based architectures to operate through and recover from periods of limited capability.

The DSGDL 1) implements an overlay network over existing cloud services to route and enforce priority requests, and 2) provisions on-demand computing nodes and sites to provide secondary capability for service requests as needed.

The first feed and second feed can extend into the aperture so that the first feed and second feed are coincident and out of phase with other. The first feed and said second feed can define a U-shaped stub, with a respective stub length, a stub width, a crossbar and a pair of stub tines defining a stub separation extending from the crossbar. The first feed and second feed can extend into the aperture so that each of the stub tines from a first feed are coincident the stub tines from the second feed. With this configuration, and with further selection of the said respective stub lengths, stub widths and stub separations, a symmetric omnidirectional radiation can be established for the antenna.

Capacitive-fed monopole antenna
A monopole antenna structure disclosed herein includes a ceramic block with a metallic surface coupled to a feed structure and a planar radiation element electrically floating relative to the ceramic block. The planar radiation element is in a parallel plane alignment with the metallic surface of the ceramic block. When the feed structure provides signal of one or more select frequencies to the metallic surface of the ceramic block, the ceramic block radiates (e.g., transmits a carrier wave) and in turn, excites the planar radiation element to re-radiate the signal.
An antenna is provided including an electromagnetic metasurface. The electromagnetic characteristics of the antenna are dynamically tunable.
