TL;DR: In this article, a consistent formulation describing the absorption of microwaves in electrically conductive materials under different microwave heating conditions is developed, and a special case when conductive powder particles are surrounded by insulating oxide layers is investigated in detail using the effective medium approximation.

TL;DR: In this article, a line of gyrotrons ranging in frequency from 24 to 84 GHz with the output power from 3 to 35 kW continuous wave, and a series of gyrotron-based systems have been developed by the Institute of Applied Physics, Nizhny Novgorod, Russia, jointly with GYCOM.

TL;DR: In this article, identical samples of ZnO powder compacts were microwave heated at three distinct widely separated frequencies of 2.45, 30, and 83 GHz and the core and surface temperatures were simultaneously monitored.

TL;DR: The results of a study of ultra-rapid (flash) sintering of oxide ceramic materials under microwave heating with high absorbed power per unit volume of material are presented and an analysis of the experimental data (microwave power; heating and cooling rates) along with microstructure characterization provided an insight into the mechanism.

TL;DR: In this paper, the influence of microwave radiation on the diffusion process in two different semiconductor materials, namely, InGaAs heterostructures with quantum wells and boron-ion implanted silicon, was investigated in a 30 GHz gyrotron device for microwave processing of materials.
