Design of Wireless Automatic Synchronization for the Low-Frequency Coded Ground Penetrating Radar
Journal of Electrical and Computer Engineering, 2015 Low-frequency coded ground penetrating radar (GPR) with a pair of wire dipole antennas has some advantages for deep detection. Due to the large distance between the two antennas, the synchronization design is a major challenge of implementing the GPR ...

Electromagnetic signatures of far-field gravitational radiation in the 1+3 approach [PDF]
Class. Quantum Grav. 32, 015011 (2015), 2014 Gravitational waves from astrophysical sources can interact with background electromagnetic fields, giving rise to distinctive and potentially detectable electromagnetic signatures. In this paper, we study such interactions for far-field gravitational radiation using the 1+3 approach to relativity.

Electromagnetic complementary media with arbitrary geometries and non-conformal boundaries
AIP Advances, 2014 A generalized folded transformation procedure is presented for the space with arbitrary shapes. General expressions for the constitute parameters of complementary media are deduced, which can be readily applied to design complementary media based ...

On the Phenomenology of Tachyon Radiation [PDF]
Found.Phys.Lett. 8 (1995) 127-134, 1995 We present a brief overview of the different kinds of electromagnetic radiations expected to come from (or to be induced by) space-like sources (tachyons). New domains of radiation are here considered; and the possibility of experimental observation of tachyons via electromagnetic radiation is discussed.
