Abstract: Techniques for applying torque to microscopic paramagnetic structures in a body includes exposing a body simultaneously to a first magnetic field oscillating at a first frequency in a first direction and a different second magnetic field oscillating at a second frequency in a second direction. The body includes a plurality of microscopic paramagnetic structures for which magnetic susceptibility to the first magnetic field is different from magnetic susceptibility to the second magnetic field. Such techniques are effective for ameliorating a symptom of a disease in an animal in which disease agents or diseased cells selectively include microscopic paramagnetic structures, including malaria.

Abstract: An antenna array (e.g., microstrip patch antenna) operates in a manner that exploits the particular susceptibility of the mutual coupling effects between radiating elements in the array. Various differential-mode excitation schemes are provided for determining optimal differential-mode voltages or optimal differential-mode currents that are applied to the radiating elements (e.g., microstrip patches) to thereby achieve certain desirable radiation characteristics including, for example, aiming a radiated beam in a prescribed direction, steering the beam, shaping the radiated beam, and/or optimizing the gain of the antenna in a specified direction.
