The recovery of information from the so called electromagnetic evanescent waves seems to be a very well explained item. Nevertheless, the travelling waves that becomes from the evanescent waves emerge from integral or differential equations that are

In this study, we propose applying a newly developed technology for the substitution of metamaterials with electromagnetic time reversal procedures to some nanotechnology issues. Metamaterials are also a new exciting field of physics research and hav

In 2020, a pandemic began, which stopped many of the academic activities around the world; in our university the emerging distance education program PEER by its acronym in Spanish, was implemented which allowed continuity to academic activities of th

In medical and laboratory procedures used to obtain useful information to diagnose a disease it is very important not to cause harm to the patient. In the detection of heart disease in fetuses in the mother’s womb, a safe and non-invasive procedure

We apply a new tool that is the Maxwell-Fredholm equations, to study the collision of an electromagnetic pulse with a flat surface of separation between the two parts of a torus-shaped artefact with a highly anisotropic refractive index that forces i

The time reversal phenomenon in sound waves for the discrete case is revisited. Our purpose is to improve a previous explanation of this problem in which there was a more limited scope. We develop a formulation which includes sink terms in the time r

Subwavelength focusing (SF) is a very useful tool that can be carried out with the use of left hand materials for optics that involve the range of the microwaves. Many recent works have described a successful alternative procedure using time reversal
