An absorption sheet for absorbing power from an electromagnetic wave generated by a device under test includes a substrate and an array of absorption elements. Each absorption element includes a conductive portion and a resistive portion. A system for performing a radiation characterization includes the absorption sheet. A method of measuring a radiative near field of a device under test and a method of characterizing a radiative near field of a device under test are also disclosed.

A non-destructive method and device for analyzing a sample comprising transparent living and/or dead cells, by 5 means of a digital holographic microscope, where the sample () is exposed to light from a laser (). The light that travels through the cells in the sample will experience a difference in the optical path length compared to the surrounding media and the wave front that emerges from the 10 cells will thus be phase shifted. This distortion can be detected in the digital hologram, which is reconstructed from the interference pattern detected by a digital sensor (), such as a CCD or a CMOS, as phase differences or phase shifts and thereby creating a digital hologram. The 15 phase shift of each element of the hologram is then used for analyzing the characteristics of the cells in the sample.

Method and apparatus for analysis of a sample of cells

The invention provides an improved array antenna, an array antenna system and an improved method for utilizing the improved array antenna and array antenna system. This is accomplished by an array antenna comprising a region of reference potential, e.g. a ground plane, and a spatially extended collection of at least two antenna elements capable of being at least partly balanced driven and at least partly unbalanced driven. The antenna elements have a first radiating element connected to a first port and a second radiating element connected to a second port. In other words, the antenna element has at least two ports. The radiating elements are arranged substantially adjacent and parallel to each other so as to extend at least a first distance approximately perpendicularly from said region of reference potential. The antenna element is further comprising a radiating arrangement connected to said first and said second radiating elements so as to extend at least a second distance above and approximately parallel to said region of ground reference.

An antenna structure including an antennawith an outer main surface, where said antennais integrated in a surface of a surrounding material. Further comprising a transition zonearranged along the perimeter of the main surfaceand overlapping the main surface, where the transition zonecomprises a layer of a resistive material with a resistivity that varies with the distance from an outer perimeter of the transition zoneto enable a smooth transition of the scattering properties between the antennaand the surrounding material
