Here, a shell structure is provided surrounding the microstructure to be produced, with the source structure being created as the shell structure or the shell structure is produced using the source structure, and subsequently the target material is inserted into the shell structure.

Abstract: A method for the spatially resolved introduction of an intensity pattern of electro-magnetic radiation by at least one optic display system into a photosensitive substance having properties which can be changed by photon exposure. These properties include a first, liquid and at least one second state, with the electro-magnetic radiation being conducted via the optic display system into the photosensitive substance and here being projected on predetermined spatial coordinates, in order to create at or in an area of these spatial coordinates a change of the properties of the substance. A surface of an objective lens of the optic display system, through which the electro-magnetic radiation 4 is emitted, is immersed in the liquid photosensitive substance 2. A corresponding device is provided, and the device and method can be used for the creation of micro or nano-scaled structures.

Abstract: The invention relates to an optical element, a method for the production thereof, and the usage thereof as an isolator or polarizer. An inventive optical element for a frequency window of the electromagnetic spectrum comprises a first component which has the function of a quarter wavelength plate, and a second component joined thereto which has a circular dichroism. When the first component is exposed to a linearly polarized wave, the optical element can be used as an optical isolator. When, however, the second component is exposed to the linearly polarized wave, the optical element can be used as an optical polarizer. An inventive optical element which is used as an optical isolator can be deployed in laser systems to reduce or suppress the feedback of the laser. In addition, windows can be thus produced which in a specific frequency window are transparent in only one direction. Unidirectional thermal insulation is thereby produced for the infared wavelength region.

Abstract: A device is described for igniting an air-fuel mixture in an internal combustion engine using a high-frequency electric power source having a coaxial waveguide structure (5) into which the high-frequency electric power may be coupled and whose one end protrudes into the individual combustion chamber of a cylinder of the internal combustion engine. The one end of the coaxial waveguide structure (5) is designed as an igniter (7a) in such a way that, when a voltage potential is applied, a field structure (22), protruding into the combustion chamber, and thus a free-standing plasma in the air-fuel mixture at the inner conductor (7, 7a), projecting from the waveguide structure, is generatable via an abrupt and/or smooth cross-section change (21) of the inner conductor (7) and/or the outer conductor (6).
