Many proposed extensions of the standard model of particle physics predict the existence of weakly interacting sub-eV particles (WISPs) such as hidden-sector photons and axions, which are also of interest as dark matter candidates. In this paper we propose a novel experimental approach in which microwave photonic lattice structures form part of a ‘light shining through the wall’-type experiment...

Microwave imaging is an alternate breast cancer detection technique that uses microwaves to generate images based on di erences in permittivity and conductivity. The large di erences in permittivity and conductivity between normal and malignant breast tissue should allow for more reliable detection of breast cancer as opposed to conventional X-ray techniques. This project aims to develop a 3-D ...

Through-wall-radar imaging is of interest for mapping the wall layout of buildings and for the detection of stationary targets within buildings. In this paper, we present an easy single-side two-location spotlight imaging method for both wall layout mapping and stationary target detection by utilizing multiple-input multiple-output (MIMO) through-wall-radar. Rather than imaging for building wal...

UWB radar system facilitates us to estimate positions and shapes of the objects behind the wall. It has a great utilization especially for rescue and security applications. This paper briefly describes all signal processing steps that are required for Imaging of the objects scanned by ultra wideband radar device. It involves the description of the basic scanning method, data preprocessing and c...

Among imaging sensors, RADAR, an acronym for RAdio Detection And Ranging, is generally used in different modes. The radar system transmits a microwave signal directing towards the region of interest and detects the signal backscattered by the surface. Due to long wavelength, microwave signal can penetrate through cloud cover, haze, dust and heavy rainfall. This property of microwaves helps in a...

We demonstrate a detection method for microwave spectroscopy on magnetization reversal dynamics of nanomagnets. Measurement of the nanomagnet anisotropic magnetoresistance was used for probing how magnetization reversal is resonantly enhanced by microwave magnetic fields. We used Co strips of 2 μm × 130 nm × 40 nm, and microwave fields were applied via an on-chip coplanar wave guide. The method...

The spectacular progress in the eld of ultracold quantum gases is intimately connected with the availability of sophisticated techniques for quantum-level control of internal states, motional states, and collisional interactions. Atom chips provide such control in compact, robust, and scalable setups, which makes them attractive for both applications and fundamental studies. In this thesis I re...
