ABSTRACT The influence of nano-metal films on the Goos-Haenchen shift (GHS) is investigated. The films deposited at the total reflecting surface of a perspex prism/air have a sheet resistance varying between Z = 25 and 3 000 Ohm. A resonance-like enhancement of the shift and of the absorption is found for TE polarized waves, when the sheet resistance approaches the value of the vacuum impedance. For TM waves the influence of the metal films on the GHS is comparatively weak. The experiments are carried out with microwaves. Keywords: Goos-Haenchen shift; nano-metallic films, microwaves PACS: 42.25.Bs, 42.25.Gy, 42.50.-p, 73.40.Gk Comment: 6 pages, 4 figures

    ABSTRACT: Fifty years ago Hartman studied the barrier transmission time of wave packets (J Appl Phys 33:3427–3433, 1962). He was inspired by the tunneling experiments across thin insulating layers at that time. For opaque barriers he calculated faster than light propagation and a transmission time independent of barrier length, which is called the Hartman effect. A faster than light (FTL or superluminal) wave packet velocity was deduced in analog tunneling experiments with microwaves and with infrared light thirty years later. Recently, the conjectured zero time of electron tunneling was claimed to have been observed in ionizing helium inside the barrier. The calculated and measured short tunneling time arises at the barrier front. This tunneling time was found to be universal for elastic fields as well as for electromagnetic fields. Remarkable is that the delay time is the same for the reflected and the transmitted waves in the case of symmetric barriers. Several theoretical physicists predicted this strange nature of the tunneling process. However, even with this background many members of the physics community do not accept a FTL signal velocity interpretation of the experimental tunneling results. Instead a luminal front velocity was calculated to explain the FTL experimental results frequently. However, Brillouin stated in his book on wave propagation and group velocity that the front velocity is given by the group velocity of wave packets in the case of physical signals, which have only finite frequency bandwidths. Some studies assumed barriers to be cavities and the observed tunneling time does represent the cavity lifetime. We are going to discus these continuing misleading interpretations, which are found in journals and in textbooks till today.

    ABSTRACT: In the thirties of the last century it was shown that nano-metal films have a frequency independent absorption in the far infrared regime and below. Moreover, the absorption A of these films is 0.5 and at the same time both reflection R and transmission T are 0.25, complying with the relation A + R + T = 1 at a sheet resistance Z□of 60 πΩ. The latter property of nano-metal films was shown by Woltersdorff in 1934. Multiple reflections between such films allow the design of low reflecting large scale absorbers for the wave length range from far infrared to low frequency radio waves. Experimental data of the novel absorber device measured in the GHz frequency range are presented. The electrical nano-metal film properties are also useful for applications in IR-photonics and IR-communication systems. The article presents a brief review of the historical studies on free carrier electromagnetic wave absorption and on novel applications.

    ABSTRACT: Investigation on the phase shifts of higher-order reflected light from a two-dimensional photonic crystal (PC) demonstrates that the phase shift of − m th order reflected light is symmetric with respect to the line of k x = m π ∕ b in the frequency-wave vector domain, where k x and b denote the incident wave vector component along the surface and the period of the PC along the surface, respectively, and m is an integer. Such phase symmetry originates from the periodicity of a PC along the surface. When higher-order propagating waves appear between two band edges of a stop band, the phase change of the 0th order reflection is generally not π as reported before. Moreover, the reflection phase can be adjusted and designed by changing the cylinder radii of the surface layer. It provides a robust way to achieve a giant Goos–Hänchen shift, which is described in detail as an example, and superluminal propagation from a PC.
