“…Therefore, each functional block exhibits an identical spatial frequency through the aforementioned arrangement of the mesh patterns. Consequently, the presence of the HEMS circuit does not cause any visual quality degradation such as Moiré and haze [26] when placed above OLED displays or liquid crystal displays (LCDs). The final dimensions of the diamond-grid mesh structure are determined based on numerical analysis to optimize the trade-off between the optical transparency and RF sheet resistance.…”

“…2) From the touch sensor perspective, a separate metallic layer (antenna layers) located near the touch sensors dramatically reduces the mutual capacitance change ratio [25], which is highly correlated to touch sensitivity, according to the presence or absence of fingers. In addition, the presence of two separate electrode layers not only reduces the entire optical transparency of display components but also causes visual quality issues such as Moiré and haze [26] due to the spatial frequency difference between two different periodic-patterned layers. Considering the fact that present-day cellular devices have to be equipped with displayintegrated touch sensors, this configuration limits the potential level of integration and functional expansion.…”

There have been scarce interactions between microwave circuits and display technologies over the past few decades. However, the two share many similarities leaving room for integration and co-development. Hence, we present a Circuit-on-Display (CoD) concept that dually functions as a radiofrequency transceiver and a high-resolution touch screen display. The approach is realized through a flexible, invisible hybrid electromagnetic sensor (HEMS) which is situated inside a high-resolution display panel. The CoD is integrated within a real-life millimeter-wave 5G NR Android-based cellular handset prototype to demonstrate a foreside beamforming coverage and a touch operation with high-resolution and optimal image quality. The devised HEMS prototype independently features flexibility, optically invisibility (transmittance >88%), and multi-functionality (system gain of 20.72 dB, beam scanning range of ±40°, and mutual capacitance change ratio >4.42%). The devised approach provides a new class of approach to enable microwave integrated circuits for new generation wireless electronics.

“…The methods of thin sectioning of samples of biological material for electron microscopic observation have improved during recent years to the extent that it is now feasible to cut, mount, and examine an intact strip of serial sections (Porter and Blum, 1953;Gay and Anderson, 1954;Karrer, 1954;Williams and Kallman, 1954). The purpose of examining micrographs of serial sections is to enable one to reconstruct in three dimensions the structural details initially contained in an appreciable depth of the sectioned material.…”

A method of securing serial sections for electron microscopy is described. Serial sections present certain anomalies of interpretation of a nature such that a complete and detailed three-dimensional reconstruction of the sectioned tissue cannot be made. These anomalies are discussed, as well as those which have been encountered in the interpretation of single sections. Observations of the following kinds have been made in an attempt to elucidate the interpretation of single and serial sections: differing methods of mounting adjacent sections, observation of the same section by high-angle stereoscopy, and examination of sections which have been shadowed prior to and subsequent to electron microscopy. It is found that the appearance of sections is independent of the choice of side to be placed against the formvar films. Stereoscopy shows that the appearance of fine structures is strongly dependent upon the direction of the penetrating electron beam with respect to the plane of the structures. Stereoscopy, combined with shadowing, shows quantitatively that extensive sublimation of polymer occurs upon normal exposure in the electron microscope. Observation of sections shadowed prior to electron microscopy indicates that varying amounts of material are removed between sections by the action of microtomy; i.e., it is probable that the sum of the thicknesses of several serial sections is considerably less than the total thickness of material removed from the block. It is believed that this effect, combined with the effect of sublimation, aids in explaining the failure of adjacent sections to exhibit continuity in their detailed structures.
