“…Periodic structures have been a matter of great interest due to the merit of introducing pass bands and stop bands [6][7][8][9] or [6] and [9]. These bands are identified and the level of the propagation and the attenuation is determined by dispersion analysis of the periodic structure.…”

“…The iris is located exactly in the middle of the main metallic cylinder the way that the unit cell is symmetric with reference to the central plane. The unit cell was analyzed by Eigen analysis method of Bostani-Webb [6], [7] and [8] after several iterations to find the right dimensions. The Block diagram is presented in the results Section.…”

In this paper a major modification in home microwave ovens is proposed in which the food status determines the time required for reheating or even cooking the food inside the microwave instead of speculating the length of the time required to achieve the desired status. The proposed microwave called “smart microwave” features a real time temperature monitoring system, which is in charge of monitoring the food inside the microwave using some infrared sensors. It also features a PID (proportional integral derivative) controller that uses the measured temperature as the processed value which is basically the feedback that goes to the processing unit of the controller to assure that the food follows the temperature profile of the set point defined by the user. The smart microwave oven also features an electromagnetic band gap structure in order to make sure that the radiation inside the microwave cavity does not compromise the accuracy of the temperature readings caused by its parasitic effects. The fabrication process of the prototype for the proposed design is also reported in this paper. The proposed smart microwave changes the nature of this device that has always been used only for reheating the food ever since it was introduced to the market as a fast cooking appliance than can take any recipe and accomplish it in no time.

“…W ITH the rapid development of information science and technology, more and more complex electromagnetic problems have emerged. Under this circumstance, a class of multi-scale electromagnetic problems with fine structures [1], [2] appears, such as electromagnetic coupling problems with small holes or slits, including the shielding of high-frequency circuits [3], [4], the protection of strong electromagnetic pulses generated by lightning [5] or nuclear explosions [6], microwave leakage [7], and so on. For such problems, if the whole domain is divided by coarse grid, the electromagnetic characteristics of the fine structure cannot be accurately reflected due to low computational precision.…”

<p>Multiscale problems with fine structure, involving electrically small fine details and relatively uniform areas, are posing significant challenges to any single algorithm in computational electromagnetics. Thus, a hybrid method combing the finite-difference time-domain (FDTD) method with the preciseintegration time-domain (PITD) method is proposed to handle such problems in this letter. For the hybrid method, the field values in the FDTD and PITD domains are calculated separately and independently. The information exchange between two solution domains is achieved by correcting the interface field components via the upwind condition. Several numerical experiments demonstrate the advantage of the hybrid method.<br> </p>
