It is demonstrated that a theory of zero-order mode resonator (ZOR) metamaterial (MTM) structure can be used for the development of a novel class of applicators for microwave thermotherapy, for example, for hyperthermia in cancer treatment or for physiotherapy. The main idea of creating such an applicator is to generate and radiate a plane electromagnetic (EM) wave into the treated biological tissue, at least in a certain extent. The main aim of this paper is to investigate whether an EM wave generated by ZOR MTM structure and emitted into the biological tissue can produce a homogeneous SAR distribution in the planes parallel to the applicator aperture and achieve a penetration depth approaching the theoretical limit represented by SAR distribution and penetration depth of an ideal EM plane wave. EM field distribution inside a virtual phantom of the treated region generated by the applicator that is based on the proposed ZOR MTM principle is investigated using a well-proven full-wave commercial simulation tool. The proposed applicator type shows both a low unwanted leaked electromagnetic field and a fairly homogeneous electric field in its aperture as well as in the virtual phantom of the treated region.

Tandem scanning reflected light (TSRLM) confocal microscopy permits the imaging of optical sections through translucent material in real time. We are currently using a TSRLM microscope to examine the morphological components of biological tissue. Optical sections of either stained or unstained biological specimens can be rapidly obtained by a through focus series of a potentially dynamic specimen. Each optical section shown here is an average of 256 512X512x8 bit frames collected from a silicon intensified target camera at video rates.Unstained living frog muscle fibers were imaged with sufficient contrast to obtain 1μ optical sections traversing a total distance of approximately 80μ. Fig. 1 shows 4μ sections through a blood vessel. Frog red cells can be clearly seen in panels 1c-e. Frog muscle fibers were mounted and stretched to a defined length. The total fiber volume was easily imaged by progressive 1μ sections.
