Such an electromagnetic wave absorber may be applied to fields where existing electromagnetic wave absorbers have been applied in order to reduce the multiple reflection of electromagnetic waves, as a simpler structure that is easily manufactured and has low cost. In particular, since the absorption ...
and Sheng Xi. Research in applied transformation based electromagnetics The interactions of electromagnetic wave with a general class of spherical cloaks based on a full wave Mie scattering model is establish analytically. We show that for an ideal cloak the total scattering cross section is absolutely...
Devices have been proposed for two-dimensional (2D) wave propagation of transverse magnetic waves that use special coordinate transformations combined with eikonal-limit approximations (that is, neglecting the impedance gradient) that allow elimination of the out-of-plane magnetic response, and thus ...
A one-way street for electromagnetic waves A hallmark of the quantum Hall effect, and a consequence of nontrivial topology of the electronic properties of systems manifesting this phenomenon, is the existence of so-called chiral edge states. These are a class of unique electronic states through ...
problem for which we will develop ideas which in general can also be used to study a wider class of related problems. The inverse problem we consider is, given the far field pattern for one or several incident plane waves and knowing that the scatterer is sound-soft, to determine the ...
The test is performed by applying damped oscillatory mag- netic field (sinusoid waves) of defined strength to the equip- ment to be tested. Waveform specification "Low frequency" "High frequency" Test level 1 2 3 4 5 x Pulse magnetic field strength A/m (peak) not defined not defined ...
The phenomena by which energy in the form of electromagnetic waves emanates from a source into space. 2. Energy transferred through space in the form of electromagnetic waves. NOTE— By extension, the term “electromagnetic radiation” sometimes also covers induction phenomena. (IEC 60050(161)–...
A frequency-selective electromagnetic wave shielding material is used for shielding areas or devices from electromagnetic waves. The electromagnetic wave shielding material has a substrate with a plur
the edge length of each aperture12in the embodiment of the present invention does not depend on the wavelength of electromagnetic waves to be transmitted and received, and thus, it is possible to configure apertures far smaller than those of the prior art. By configuring the apertures12in the ...
