A spherical water-rich load (potato) is placed on the rotating glass tray of a microwave oven some distance from the center of rotation. 1 kW of 2.45 GHz microwave power is applied via a waveguide feed. The plate rotates at 9 degrees per second. The heat transfer model involves the ... 詳細を見る
A 180° Ring Hybrid (Rat-Race Coupler) is a four-port network with 180° phase difference between two ports. It is cheaper to manufacture this type of microstrip line component compared to a wave guide 180° hybrid junction, so called magic-T. The objective of this model is to compute the S ... 詳細を見る
In this model, the transmitter (microstrip patch) and receiver (Yagi–Uda) antennas are modeled simultaneously in the FEM domain and are coupled with FEM–BEM coupling. The results are compared with the analytical Friis transmission formula. In detail, the emw and emw2 interfaces find out ... 詳細を見る
It is possible to shape the radiation pattern and steer the beam from an antenna array by controlling the relative phases and magnitudes of the input signal. This example shows how to design an active electronically scanned array (AESA) using arithmetic phase progression on each antenna ... 詳細を見る
A Biconical antenna is a type of wideband antenna with omni-directional radiation pattern in the H-plane similar to a dipole antenna. A coaxial feed is connected to the radiators using two 90 degree bent arms. The model shows that the biconical antenna works well in applications ... 詳細を見る
The marine controlled source electromagnetics method (CSEM) for oil prospecting has emerged as a promising technique during recent years. This model demonstrates one variant of it. It uses a mobile horizontal 1 Hz electric dipole antenna that is towed 150 m above the sea floor. An array ... 詳細を見る
A helical antenna has two major modes. One is normal mode and the other is axial mode. When the helical antenna is operating at the normal mode, its far-field radiation pattern is similar to the torus shaped pattern of a classic dipole antenna. At the axial mode, the helical antenna is ... 詳細を見る
In this model, we introduce a cloaking method using an electrically tuned monolayer of graphene. We will show that when a cylindrical dielectric scatterer is covered in graphene, the scattering cross section is greatly reduced at the designated frequency, making it electromagnetically ... 詳細を見る
A radome minimizes losses and improves radiation characteristics of an antenna through its design. The structure can be optimized to minimize the transmission loss and also designed to improve radiation characteristics including antenna directivity and side lobes. Shown in the model is ... 詳細を見る
A parallel wire transmission line is composed of two conducting wires in a dielectric such as air. The fields around such a transmission line are not directly confined by the conductors, and extend to infinity, although they drop off in rapidly away from the wires. This model ... 詳細を見る
