Although metamaterials and so-called left-handed media have originated from theoretical considerations, it is only by their practical fabrication and the measurement of their properties that they have gained credibility and can fulfil the potential of their predicted properties. In this review we consider some of the more generally applicable fabrication methods and changes in geometry as they have progressed, exhibiting resonant frequencies ranging from radio waves to the visible optical region.

We developed the LIGA process using a compact synchrotron radiation (SR) source and ceramics micro fabrication process. These processes realized an array of lead zir-conate titanate (PZ7) rods whose cross section is 25 urn and was applied to manufacture piezocomposite for high resolution ultrasonic diagnosis for the first time. We also developed microconnector by the LIGA process.

The motif of paradise in the culture and art of the turn of the 19th and 20th centuries ranks among the most important ones, while in Vienna, apart from being so meaningful for writers (e.g. Hugo von Hofmannsthal) and artists from the Secession circle (Gustav Klimt, Josef Hoffmann, Josef Maria Olbrich and others), it was also important to Oskar Kokoschka. This can be well seen in the poetical lithograph-illustrated fairy tale Die Träumenden Knaben, designed by him as a Gesamthkunstwerk in 1907/8. In the text- and image-layer, the youthful work deeply rooted in the tradition, drew inspiration from e.g. the ideas of J. W. von Goethe and Adalbert Stifter.

Celem niniejszego artykułu jest zwrócenie uwagi na niedoceniany fenomen obrazów fabrycznych. Ze względu na obszerność materii rozważania ograniczono do przybliżenia technik produkcji (litografii, fotolitografii, offsetu), a także wariantów zdobień i ramowania. Pracę nad tematem oparto na badaniach terenowych i muzealnych, zaś badania bibliograficzne – na tekstach badaczy niemieckich. Wynika to z faktu, że niemieccy wytwórcy obrazów byli w swoim czasie potentatami na rynku europejskim. Wyrób reprodukcji obrazkowych rozpowszechnił się tak dalece, że bez przesady można w tym przypadku stosować sformułowania typu produkcja czy obraz fabryczny. Historia popularnych wydawnictw związana była z postępem technologicznym. Dzięki rozwojowi technik poligraficznych obrazy zaczęto wykonywać w ilościach hurtowych. Szybko i naturalnie obrazy fabryczne stały się reprezentacyjną sztuką chłopów i robotników.

The main goal of the article is to draw attention to the underestimated phenomenon of printed paintings. Due to the extensiveness of the matter, the considerations are limited to the study of the production technology (primarily lithography, secondarily photolithography and offset printing), as well as variations of embellishments and framing. The study of the subject was based on field and museum researches, while bibliographic research based primarily on texts of German researchers. This results from the fact, that at the time German producers of graphic images were potentates on the European market. What is more, manufacture and distribution of painting reproductions spread so widely, that without exaggeration, we can use the expressions like “the manufacture” or “the manufactured painting”. The history of the most popular series of paintings were connected with the technological progress. Thanks to the development of printing-techniques the images could be produced in wholesale-quantities. Quickly and naturally the manufactured painting became a representative art of peasantry and blue-collar workers.

Lipid multilayer microarrays are a promising approach to miniaturize laboratory procedures by taking advantage of the microscopic compartmentalization capabilities of lipids. Here, we demonstrate a new method to pattern lipid multilayers on surfaces based on solvent evaporation along the edge where a stencil contacts a surface called evaporative edge lithography (EEL). As an example of an application of this process, we use EEL to make microarrays suitable for a cell-based migration assay. Currently existing cell migration assays require a separate compartment for each drug which is dissolved at a single concentration in solution. An advantage of the lipid multilayer microarray assay is that multiple compounds can be tested on the same surface. We demonstrate this by testing the effect of two different lipophilic drugs, Taxol and Brefeldin A, on collective cell migration into an unpopulated area. This particular assay should be scalable to test of 2000 different lipophilic compounds or dosages on a standard microtiter plate area, or if adapted for individual cell migration, it would allow for high-throughput screening of more than 50,000 compounds per plate.

In this paper we introduce a diffractive structure with a geometry which contains multiple Fresnel zone plates (MFZP) disposed in an arrangement based on a fractal-like rule. The corresponding diffracted intensity in planes perpendicular to the propagation axe presents two or more focal points. Their position and magnitude depend on geometrical parameters of the MFZP and on dimensions in the fractal-like arrangement. In our simulations we also analyze the influence in diffraction pattern of different non-binary phase levels in the MFZP plane. The MFZP structures with different values of geometrical and phase parameters are addressed to an optoelectronic device liquid crystal spatial light modulator (LCSLM), the experimental and simulation results are in a good agreement. The MFZP geometry with better optical parameters in diffraction pattern is then made on glass using electron beam lithography technique.

Drukowanie offsetowe jest techniką pochodną drukowania płaskiego, którego poprzednikiem była litografia (z greckiego lithos – kamień, grapfo – pisać) – inaczej drukowanie z kamienia litograficznego.

Simulation of the surface plasmon polariton (SPP) distribution in the 10 μm long four-channel multiplexer is conducted in present paper. The excitation of the SPP was done using the 632.8 nm pulse laser with 50 fs pulse duration. The simulation processes of the SPP propagation in the fourchannel multiplexer were performed for the latter switched as a splitter as an adder. Though the obtained signal strength is low due to ohmic losses and signal reflections in the middle of the waveguide it is possible to registrate it. The detailed procedure of waveguides preparation, analysis and registration of SPP propagation is described in the paper. For the proposed model verification the two-channel 20 μm long splitter was formed by optical projection lithography. Studies have shown that the SPP is distributed throughout the whole structure of the 20 μm long two-channel splitter with a partial extinction due to ohmic losses.
