Visualizing Small Objects Using Amplitude-Modulated Laser Light at Microwave Frequencies

Targeted treatment of cancer with radiofrequency electromagnetic fields amplitude-modulated at tumor-specific frequencies

In the past century, there have been many attempts to treat cancer with low levels of electric and magnetic fields. We have developed noninvasive biofeedback examination devices and techniques and discovered that patients with the same tumor type exhibit biofeedback responses to the same, precise frequencies. Intrabuccal administration of 27.12 MHz radiofrequency (RF) electromagnetic fields (EM...

Dielectric Properties of Materials at Microwave Frequencies

KŘIVÁNEK, I.: Dielectric properties of materials at microwave frequencies. Acta univ. agric. et silvic. Mendel. Brun., 2008, LVI, No. 5, pp. 125–132 The paper introduces the review of the present state of art in the measurement of the interaction of electromagnetic waves with diff erent kinds of materials. It is analysis of the possibilities of the measurement of the interaction of high frequen...

Grating-coupled surface plasmons at microwave frequencies

This work presents a detailed investigation of electromagnetic coupling to the surface plasmon-polariton ~SPP! at microwave frequencies. We have recorded the wavelength-dependent reflectivity from a metallic sinusoidal diffraction grating of pitch 15 mm. In order to minimize the problems associated with nonplanar incident wavefronts, we have developed an apparatus that collimates the incident b...

Metamaterial electromagnetic cloak at microwave frequencies.

A recently published theory has suggested that a cloak of invisibility is in principle possible, at least over a narrow frequency band. We describe here the first practical realization of such a cloak; in our demonstration, a copper cylinder was "hidden" inside a cloak constructed according to the previous theoretical prescription. The cloak was constructed with the use of artificially structur...
